A Pentium 166 UP server at my Univeristy is running 2.0.33 + 2 ip_frag
patch + my vmalloc patch, and is locking every few hours. This seems
started happening after adding 64Mbyte of ram to the machine (now has

I used my backport of the print_eip patch to understand where the lock
happens and it happens always in the same place.

The kernel is started by a do_page_fault() that then run a do_no_page()
and continue with ret_from_sys_call. Then the kernel lock after the
RESTORE_ALL before signal_return: in entry.S.

Make sense to you? What' s trying to do the do_no_page()?

We tried memtest86.bin and it reported no ram hardware errors...
