I have had 7 of these under 2.1.9[01], all when the experimental
Zornetzer kmod was trying load the lp/parport module stack.


Mar 28 18:38:42 shawc kernel: Linux version 2.1.91 (root@shawc) (gcc
version 2.7.2.3) #13 Sat Mar 28 17:10:08 GMT 1998
Mar 28 18:38:57 shawc kernel: trying:parport_probe
Mar 28 18:38:57 shawc kernel: get_unused_fd: slot 3 not NULL!


I have also had 4:


Mar 28 14:31:23 shawc kernel: free_one_pmd: bad directory entry 000000cc
at the same place.


But it doesn't happen every time, so some random trashing somewhere?
