Problem Description:
00:0d.3 USB Controller: ALi Corporation USB 2.0 Controller (rev 01)
  This is a PCI USB 2.0 card.  On a cold start (system powered off, the ehci_hcd
driver has no problems initializing it.  On a warm start (reboot, shutdown -r
for example) it fails to initialize with the following kernel errors:

ACPI: PCI Interrupt 0000:00:0d.3[A] -> GSI 17 (level, low) -> IRQ 16
ehci_hcd 0000:00:0d.3: EHCI Host Controller
ehci_hcd 0000:00:0d.3: new USB bus registered, assigned bus number 5
ehci_hcd 0000:00:0d.3: can't setup
ehci_hcd 0000:00:0d.3: USB bus 5 deregistered
ehci_hcd 0000:00:0d.3: init 0000:00:0d.3 fail, -110
ehci_hcd: probe of 0000:00:0d.3 failed with error -110

The FAQ will remind you to report USB problems with CONFIG_USB_DEBUG 
set, so that interesting debug status gets reported.  :) 
 
FWIW I had an AMD 760-MPX system for a while, with an ALI card; 
it came up just fine in that situation, I rebooted it rather 
often when debugging.

dmesg output with CONFIG_USB_DEBUG during failure

Thanks for reminding me to enable debugging.  dmesg output with
CONFIG_USB_DEBUG enabled.  I'm assuming the relevant section begins at line
446.

I was able to reboot without any problems until sometime during the 2.6.16.x
kernels.

Created attachment 9053 [details]
dmesg output with debug on successful init

diffing the two outputs shows some differences, but I don't know how
significant they are.

Andy,
Are you willing to try 2.6.22-rc4? There were fixes specifically in the USB shutdown area. Please use debug mode as before in case it is still a problem.
Thanks,

Sorry for not commenting on this earlier.  Unfortunately, I can't test this anymore.  I retired the server that had this problem and it's replacement has onboard USB 2.0 and I haven't seen this problem since then.  It's been about 9 months since I replaced the system.
