I am running knoppix 3.8.1 on an IBM thinkpad T41 with 1.25GB RAM.

I am struggling from UNIONFS failing randomly when installing packages via apt, when it gets to the post configuration scripts.

I have been watching dmesg, and it always spits out the following debug messages:

ASSERTION FAILED: rdstate->uds_cookie < MAXRDCOOKIE at /usr/src/modules/unionfs-
1.0.11/unionfs.h:256 (verify_rdstate_offset)
Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:

After this occurs, I cannot use apt-get install anymore and the process freezes and is not killable.
