pa,
When I ssh into my box I see:
---
kernel BUG at mm/shmem.c:585!

574 struct shmem_inode_info *info = SHMEM_I(inode);

586 spin_lock(&sbinfo->stat_lock);
587 sbinfo->free_inodes++;
588 spin_unlock(&sbinfo->stat_lock);

hmm I didn't mentioned till now because of some non cvs stuff in my kernel
but I got same messages (ie only "BUG at mm/shmem.c:585!") with k-2.4.23
64bits on my b2k build with latest gcc-3.3.2.
hth,
Joel
