Have 5 linux machines at home. 3 with Fedora 34 and 2
with Fedora 35. 4 did the dnf update that included
5.16.16 and rebooted fine.
The one system didn't?? Have 3 machine I vnc into, and
have one monitor that I connect when I need to look at
them.
When I couldn't get to the machine after there was
enough time to reboot, and pings failed. I connected
monitor.
When screen came up, it was sitting at grub menu.
Pressing enter had it load the 5.16.16 kernel with what
seemed no issue. Then did a restart and again, it just got
to the boot menu with no timeout? So had to press enter
again. Did that 2 more times, same results.
Reinstalled the kernel but again. Same result.
Looked at grub.cfg and didn't see anything, and
/default/grub was same as other machines?
Looked at grubenv and that was showing boot_success=0
while all other machines had boot_success=1.
On my notebook it shows as beginning.
# GRUB Environment Block
# WARNING: Do not edit this file by tools other than
grub-editenv!!!
saved_entry=189711f94e78436d9618b891a8fce70e-5.16.
16-100.fc34.x86_64
boot_success=1
boot_indeterminate=0
Tried the grub-editenv that it mentioned, but program not
found. There is a grub2-editenv, so perhaps a missed
update for the grubenv??
Help didn't show much, so was going to change the 0 to 1
with hexedit, but I looked at grubenv and it had changed
from 0 to 1 on its own in the time I took looking at things.
The other 4 machines did update with no problem, and
reboot started with no intervention. Not sure why this
one had it go to grub menu, and just sit there.
Haven't tried another reboot to see it the timeout will
work next time, or if will have to continue hitting enter
after any reboot??
Haven't had this issue with any other updates??
Thanks.
Have a nice day.
