Public bug reported:
I upgraded my computer to feisty. The actual kernel (linux-
image-2.6.20-5-generic 2.6.20.5.1) cannot mount my /home partition:
# mount /dev/sdc2 /home
mount: Operation not supported
meanwhile, dmesg is filled with lots of these:
[ 663.015843] attempt to access beyond end of device
[ 663.015847] sdc: rw=0, want=234484733, limit=66055248
[ 663.015850] attempt to access beyond end of device
[ 663.015854] sdc: rw=0, want=234484734, limit=66055248
[ 663.015858] attempt to access beyond end of device
[ 663.015862] sdc: rw=0, want=234484735, limit=66055248
/dev/sdc1 mounts fine (it is my root partition).
Also, this same partition mounts successfully under 2.6.15-26-k7 (as /dev/hda2
in that case).
Under 2.6.15 this is the boot info about /dev/hda:
