CONFIG_MK6 = lsof hangs unkillable

[Tony Mantler <nicoya@ubb.ca>]

I'm having trouble running lsof on 2.6.15.1 when the kernel is  
compiled with CONFIG_MK6. When run as root, lsof will segfault, and  
when run as a user lsof will hang unkillable.

The same kernel, same machine, but compiled with CONFIG_MK7 runs just  
lsof just fine.

some versions:
gcc version 4.0.3 20060104 (prerelease) (Debian 4.0.2-6)
lsof                       4.76.dfsg.1-1              List open files.

diff between broken and working (I can send a full .config if needed):
