[PATCH RFC] module-setup.sh: install usb serial driver for ttyUSB0
by Dave Young 27 May '16

27 May '16

In case one want to use usb serial console, we need to pack the usb serial driver into kdump initramfs so that one can see the console output on the usb console. I only handled ttyUSB0, this is like a hard code, but it should be enough for most cases. Also only install the driver for the ttyUSB0 device. Tested with adding "console=ttyUSB0" in 2nd kernel commandline. Tested latest F22 kernel, there's CONFIG_USB_SERIAL_CONSOLE=y, kdump work ok.

[PATCH] dracut-module-setup: Mute the error message when kdump detects iSCSI session by iscsiadm
by Minfei Huang 06 Dec '15

06 Dec '15

For independent hardware iSCSI HBA, the network config will be recorded in the firmware BIOS. It fails to use normal means(like iscsiadm) to detect iSCSI session details, since HBA firmware doesn't expose the session to running kernel. Mute the error message when kdump detects iSCSI session by iscsiadm.

[PATCH v2] kdump.sysconfig: add KDUMP_COMMANDLINE_REMOVE
by Dangyi Liu 15 Nov '15

Use KDUMP_COMMANDLINE_REMOVE config instead of hardcode them in kdumpctl. System admins can also specify what to remove as they like.

[PATCH RFE] kdump.sysconfig: Support KDUMP_COMMANDLINE_REMOVE
by Dangyi Liu 19 Oct '15

19 Oct '15

Some parameters need to be removed from the cmdline when kdump. These include "quiet", "slub_debug", etc. This patch allows system admins to config what to remove, since they may use a different kernel. What about some existing params? I think maybe "slub_debug" should also be put here. diff --git a/kdump.sysconfig b/kdump.sysconfig index effe466..545228a 100644 --- a/kdump.sysconfig +++ b/kdump.sysconfig @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 reset_devices" diff --git a/kdump.sysconfig.i386 b/kdump.sysconfig.i386 index bb7a6e5..0a15cd0 100644 --- a/kdump.sysconfig.i386 +++ b/kdump.sysconfig.i386 @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices numa=off udev.children-max=2 panic=10 rootflags=nofail transparent_hugepage=never" diff --git a/kdump.sysconfig.ppc64 b/kdump.sysconfig.ppc64 index dd09598..1188764 100644 --- a/kdump.sysconfig.ppc64 +++ b/kdump.sysconfig.ppc64 @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 noirqdistrib reset_devices cgroup_disable=memory numa=off udev.children-max=2 ehea.use_mcs=0 panic=10 rootflags=nofail kvm_cma_resv_ratio=0 transparent_hugepage=never" diff --git a/kdump.sysconfig.ppc64le b/kdump.sysconfig.ppc64le index dd09598..1188764 100644 --- a/kdump.sysconfig.ppc64le +++ b/kdump.sysconfig.ppc64le @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 noirqdistrib reset_devices cgroup_disable=memory numa=off udev.children-max=2 ehea.use_mcs=0 panic=10 rootflags=nofail kvm_cma_resv_ratio=0 transparent_hugepage=never" diff --git a/kdump.sysconfig.s390x b/kdump.sysconfig.s390x index b103a88..1981999 100644 --- a/kdump.sysconfig.s390x +++ b/kdump.sysconfig.s390x @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="nr_cpus=1 cgroup_disable=memory numa=off udev.children-max=2 panic=10 rootflags=nofail transparent_hugepage=never" diff --git a/kdump.sysconfig.x86_64 b/kdump.sysconfig.x86_64 index 7991d68..bf7b974 100644 --- a/kdump.sysconfig.x86_64 +++ b/kdump.sysconfig.x86_64 @@ -14,6 +14,11 @@ KDUMP_KERNELVER="" # /proc/cmdline KDUMP_COMMANDLINE="" +# This variable lets us remove arguments from the current kdump commandline. +# It's useful when KDUMP_COMMANDLINE is taken from /proc/cmdline and you want +# to remove some of them. +KDUMP_COMMANDLINE_REMOVE="quiet" + # This variable lets us append arguments to the current kdump commandline # As taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 rootflags=nofail acpi_no_memhotplug transparent_hugepage=never" diff --git a/kdumpctl b/kdumpctl index 9f7e56b..37ec3ab 100755 --- a/kdumpctl +++ b/kdumpctl @@ -105,7 +105,7 @@ prepare_cmdline() else cmdline=${KDUMP_COMMANDLINE} fi - cmdline=`remove_cmdline_param "$cmdline" crashkernel hugepages hugepagesz panic_on_warn slub_debug` + cmdline=`remove_cmdline_param "$cmdline" crashkernel hugepages hugepagesz panic_on_warn slub_debug ${KDUMP_COMMANDLINE_REMOVE}` cmdline="${cmdline} ${KDUMP_COMMANDLINE_APPEND}" -- 2.4.3

"quiet" will disable most of log messages. Since kdump is somehow unsteady and a rare condition, it's better to enable more logs.
