Bug#317581: kernel-image-2.6.11-1-k7: kernel oops while reading udf disk



Package: kernel-image-2.6.11-1-k7
Version: 2.6.11-7
Severity: important


Kernel oops while reading UDF formated DVD+RW disk. Tested on two disks:
one formated and burned with InCD on Windows and the other with linux
udftools... Both mounted "standard" way: mount -t udf /dev/hdc /tmp/1
pktcdvd module wasn't loaded. After oops drive is busy - cannot umount
and drive led is on.

hdc: tray open
end_request: I/O error, dev hdc, sector 19228
udf: udf_read_inode(ino 4807) failed !bh
Unable to handle kernel NULL pointer dereference at virtual address 00000038
 printing eip:
f10c8112
*pde = 00000000
Oops: 0000 [#1]
