pluging usb devices while suspended causes crash

[Paul Larson]

I'm able to suspend and resume on babbage 3 without any problems normally, but one of the tests I'm doing involves unplugging my usb keyboard and mouse, suspending the system, plugging the usb keyboard and mouse back in, and resuming. When I do this, I don't get an oops or anything, but the kernel does spew quite a few errors and fails to recover. I've been able to reproduce this very reliably.

Kernel version is 2.6.31.604.5

Here is the output I get from the serial console:

[Tobin Davis (gruemaster)]

I am seeing a problem with a laptop drive connected to the sata port not recovering from sleep. On resume, I get a text console full of read-error on swap-device and EXT4-fs errors on sda6 (multi-part disk with root on sda6 for this image).

[Paul Larson (pwlars)]

@Tobin - possible that you are seeing a different problem. Does the kernel output look like what you are seeing above? I am able to suspend/resume just fine with either sata, or with USB as my rootfs. The bug referenced here is a specific case of plugging usb (i.e. mouse/keyboard) while the system is suspended, then recovering.

[Tobin Davis (gruemaster)]

The kernel output is the same minus the usb messages (and the drive is sda6 instead of sdb1). I think the problem may be in the usb controller wakeup. That would affect sata as well, since it floats off the usb bus internally.

[Tobin Davis (gruemaster)]

Marking as won't fix, as the only devices still supported by this release are the buildds, so very low chance of hitting this. Lucid Arm support ended once 11.10 was released (not an LTS release).
