Public bug reported:
I dist-upgraded to Intrepid from Hardy, but now I cannot boot using the
Intrepid kernel (2.6.27-6-generic). Reiserfs reports an unreadable
block and kicks me to a root shell. Dmesg reports errors of the
following kind (full file attached):
[ 23.807828] Buffer I/O error on device sda5, logical block 67360508
[ 23.807892] attempt to access beyond end of device
[ 23.807895] sda: rw=0, want=156296315, limit=153774180
. . .
The block that reiserfs reports is bad is block 16840127, and indeed running
the following command fails and produces more dmesg errors:
dd if=/dev/sda5 of=/root/block bs=4096 count=1 skip=16840127
But the above command (as well as booting in general) works fine using the
Hardy kernels.
Here is fdisk -l output:
Disk /dev/sda: 78.7 GB, 78732380160 bytes
255 heads, 63 sectors/track, 9572 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

And here is my fstab file:
# /etc/fstab: static file system information.

# /dev/sda1

And the dmesg log will be attached. I will also momentarily post the reiser
fsck log.
