I noticed an odd message in the kernel log while booting
linux-next (tag: next-20090602[*])
attempt to access beyond end of device
sdb3: rw=0, want=31664120, limit=31664115
sdb3 is an ext3 filesystem mounted as /home
$ grep sdb3 /proc/partitions
8 19 15832057 sdb3
I think /proc/partitions in in KBytes ... so the block (512 Byte)
count for this partition is 2*15832057 = 31664114 ... so the
"limit" in the console log looks reasonable, and since the "want"
is a bigger number, it does seem that we are trying to access
beyond the device.
BUT ... I don't get this message when booting a kernel built
from Linus' tree.
