Not a git user (I need to become one but haven't found the time to read up 
on it yet), but no problem, I'll dig out the patch and try reverting it.
Luckily it seems this is pretty repeatable on every boot, I find it in the 
logs instantly after logging in and launching a shell on my KDE desktop and
running dmesg - I'll do a few more reboots to make sure it *really* is 
reproducible before reverting the patch so we can be sure if it fixes the 
problem or not.

Btw, the messages turn out slightly different on each boot, here are the 
ones from this current boot of my box:

Would gathering more of these help you out?

I have no USB, SATA or similar devices in the box, only a floppy drive, a 
SCSI harddisk, a SCSI CD writer and a SCSI DVD-ROM.
