ATI RS350 chipset

I just put together a system with a Gigabyte GA-8TRS350MT board; this has what it calls the ATI RS350 chipset. It's a pretty nice board and (so I thought) not particularly new, but it seems to be a bit ahead of current kernel support. I figured I'd post a note in case anything is searching Here's an lspci: 00:00.0 Host bridge: ATI Technologies Inc: Unknown device 7833 00:01.0 PCI bridge: ATI Technologies Inc: Unknown device 7838 00:13.0 USB Controller: ATI Technologies Inc: Unknown device 4367 (rev 01) 00:13.1 USB Controller: ATI Technologies Inc: Unknown device 4368 (rev 01) 00:13.2 USB Controller: ATI Technologies Inc: Unknown device 4365 (rev 01) 00:14.0 SMBus: ATI Technologies Inc: Unknown device 4363 (rev 03) 00:14.1 IDE interface: ATI Technologies Inc: Unknown device 4369 (rev 01) 00:14.2 IDE interface: ATI Technologies Inc: Unknown device 436e (rev 01) 00:14.3 ISA bridge: ATI Technologies Inc: Unknown device 436c (rev 01) 00:14.4 PCI bridge: ATI Technologies Inc: Unknown device 4362 (rev 01) 00:14.5 Multimedia audio controller: ATI Technologies Inc: Unknown device 4361 (rev 03) 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon 9100 PRO IGP 02:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10) I checked the curent PCI ID list on sourceforge and these aren't listed; I'd add them myself but I have no idea what to call them. FC2 (which I currently have rolled out on 200 machines) didn't install it all. FC3 did install, but the IDE was dog slow and required a little kernel patch for chipset recognition. kernel-2.6.10-1.1056_FC4 added support for that. (This is bug 142647.) Graphics seem to work under FC3 well enough. I haven't tried 3D stuff yet. I can switch to text consoles but when I do a shutdown (with X running) the screen goes completely dark until the machine reboots. USB support works for mice but when I use a plain USB2 memory thingy (any of several models I have laying around) things don't work so well. Upon inserting the device (with this morning's kernel-2.6.10-1.1063_FC4) I see: usb 3-3: new low speed USB device using ohci_hcd and address 2 ohci_hcd 0000:00:13.1: Unlink after no-IRQ? Different ACPI or APIC settings may help. which is a bit more helpful than earlier kernels. lsusb at this point hangs. Booting with noapic doesn't help; then I get this: usb 3-3: new full speed USB device using ohci_hcd and address 2 usb 3-3: device descriptor read/64, error -110 usb 3-3: device descriptor read/64, error -110 usb 3-3: new full speed USB device using ohci_hcd and address 3 usb 3-3: device descriptor read/64, error -110 usb 3-3: device descriptor read/64, error -110 usb 3-4: new low speed USB device using ohci_hcd and address 4 and lsusb still hangs. acpi=off gives the same. This is not yet in bugzilla; I'll keep experimenting and file a complete bug once I've trolled through the BIOS settings. I haven't tried sound yet. If anyone has any suggestions, I'd sure appreciate them. - J<
