ACPI S3 - USB resume problem (kernel 2.6.7)

From: Carsten Rietzschel
Date: Thu Jun 17 2004 - 10:42:28 EST

Hello,

I tried to get S3 "Suspend to RAM" working. Almost everything works now, but
USB doesn't respond after resuming (kernel 2.6.7).

The log shows (log appended; lspci -v output also):

usb 1-1: control timeout on ep0out
uhci_hcd 0000:00:10.0: Unlink after no-IRQ? Different ACPI or APIC settings
may help.
usb 1-1: control timeout on ep0out
usb 1-1: device not accepting address 2, error -110
usb 1-1: new low speed USB device using address 3
usb 1-1: control timeout on ep0out
usb 1-1: control timeout on ep0out
usb 1-1: device not accepting address 3, error -110

Noticed that in /proc/interrupts the values for uhci_hcd are not incremented
after resume. So are no IRQs where received (is that right ?).
What could be reason ?

So far I tried:
- set CONFIG_USB_DEBUG = y
- disable/enable APIC as suggested
("Unlink after no-IRQ? Different ACPI or APIC settings" goes away, timeout
stays)
- disabled USB 1.1 Controller or USB 2.0 Controller in BIOS
- disabled preemption
- compiled USB-stuff into kernel instead using as modules
( even tried to unload before suspend and reloaded after resume )
- ensured CONFIG_PM is on and resume/suspend in is
called /drivers/usb/host/uhci-hcd.c
- forced reset_hc(uhci) in uhci_suspend() instead of suspend_hc()
( comment says it's for some broken motherboards )
- I saw CONFIG_USB_SUSPEND in some source files under host and core.
I enabled it directly in these files and recompiled/restarted. No success.
(doesn't harm, but seems not ready to use:
- it's not configureable ;)
- usb_suspend/resume_device() functions are nowhere)

Nothing helped :/
Still timeout messages and no USB device works after resume.

Anybody any idea where to look next or what to search for, or even a fix ?
If you want more infos I will tell you :)

Regards,
Carsten
