From: Alexander Holler on 13 Nov 2009 18:10
Hello,

I'm having a problem with kernels (x86_64) <=2.6.32-rc7 (that means all
kernels I tried, including the latest stable 2.6.31.6) on a Gigabyte
P55M-UD4 mb (Bios F4l) with an Intel Core i7 860 and sleeping usb-hds.

I don't have the problems when using the same usb-drives on a laptop
with a core2duo (ICH8), so it seems to be a problem with the chipset
(p55-express).

The problem seems to occur when the usb-drive goes to sleep (because of
inactivity) and the kernel tries to access them afterwards.

Here are the excerpts from the log:

-------------------------------------------------------------------------

(GCC) ) #1 SMP Fri Nov 13 19:01:02 CET 2009

....

(This warning seems to be unrelated, but I'm getting this too with every
kernel I've tried, so I'm including it here)

You cut too early. This shows a failed reset but not the cause.

That sounds like the device started reporting a different firmware
string after it woke up, and the kernel decided it wasn't the same
device anymore and triggered a disconnect/reconnect..

There are no relevant messages in the log before:

I don't think it's a problem with the devices. I'm using them (more than
1) for some months now and never have had any problems. The problem
first started, when I've switched to the box with the p55-express and I
still don't have any problems with these devices on other machines.

Kind regards,
