Hi,
linux-2.6.10-ck4
gcc-3.4.4 20041128
I set up swap on an encrypted dmcrypt device.
While stressing swap usage with make -j200 in the
kernel tree, the machine crashes:
Adding 1461872k swap on /dev/mapper/swap. Priority:-2 extents:1
------------[ cut here ]------------
kernel BUG at drivers/block/ll_rw_blk.c:2193!
