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:
