2.6.0-test2: Lost USB mouse after resuming from S3

2.6.0-test2: Lost USB mouse after resuming from S3

[Michael Frank]

Causes are that usb-host controller does no handle S3 yet _plus_ possibly (depending on your hardware) 
loss of PCI interrupt links as current ACPI does not resume those.

Known issue, please unload the usb modules before suspending them.

The upcoming suspend patches will allow us to fix this "properly",
please give us a few weeks :)

I hope you have a chance to look at a uhci/usbnet problem I have found.  
If I connect and disconnect my Zaurus 5500 ...

kernel: usb0: register usbnet usb-00:1d.0-1, Sharp Zaurus SL-5x00
... [ping a few packets] ...
vista kernel: usb0: unregister usbnet usb-00:1d.0-1, Sharp Zaurus SL-5x00

I can unload uhci (kind of):

vista kernel: usb.c: USB disconnect on device 00:1d.2-0 address 1
vista kernel: usb.c: USB bus 3 deregistered
vista kernel: kmem_cache_destroy: Can't free all objects c158acd0
vista kernel: uhci: not all urb_priv's were freed
vista kernel: usb.c: deregistering driver usbdevfs
vista kernel: usb.c: deregistering driver hub
vista kernel: Swsusp 1.1-rc1: Initiating a software_suspend cycle.

and then on the resume uhci crashes on the load attempt:

vista kernel: usb.c: registered new driver usbdevfs
vista kernel: usb.c: registered new driver hub
vista kernel: uhci.c: USB Universal Host Controller Interface driver v1.1
vista kernel: kernel BUG at slab.c:815!

This does -not- happen using usb-uhci as enabled by the (0619) acpi patch:

vista kernel: usb.c: USB bus 3 deregistered
vista kernel: usb.c: deregistering driver usbdevfs
vista kernel: usb.c: deregistering driver hub
vista kernel: Swsusp 1.1-rc1: Initiating a software_suspend cycle.

...

vista kernel: usb.c: registered new driver usbdevfs
vista kernel: usb.c: registered new driver hub
vista kernel: usb-uhci.c: $Revision: 1.275 $ time 23:16:36 Aug  6 2003
vista kernel: usb-uhci.c: High bandwidth mode enabled
vista kernel: PCI: Setting latency timer of device 00:1d.0 to 64
vista kernel: usb-uhci.c: USB UHCI at I/O 0xefe0, IRQ 11
vista kernel: usb-uhci.c: Detected 2 ports

the above syslog excerpts are from 2.4.22rc1 (no acpi patch) and 2.4.21
(acpi 20030619).  Any suggestions, or hope for a fix?

thanks,

rob.

And mind the _plus_ issue - On my hardware you could debug dead interrupts 
in the host controller code forever...

Have posted a patch to fix ACPI, but no feedback as of yet ;)

>>Causes are that usb-host controller does no handle S3 yet 
What does it refer to?  ( Driver doesn't support S3? or hardware doesn't support S3?)

ps. file any acpi issue on bugme.osdl.org

Thanks,
Luming

Is being addressed by USB developers
