I just had an oops today with 2.4.21.
I've ran it through ksymoops: Unable to handle kernel NULL pointer dereference at virtual address 00000000 c013d06f *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c013d06f>] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010286 eax: c060dc54 ebx: c060dc3c ecx: 00000000 edx: c05f5bd0 esi: c060dc24 edi: ca1f8bc0 ebp: 00000179 esp: c123ff60 ds: 0018 es: 0018 ss: 0018 Process kswapd (pid: 5, stackpage=c123f000) Stack: 00000001 000001d0 00000001 00000005 c013d38b 0000049a c01271e7 00000005 000001d0 00000005 000001d0 c02be394 00000000 c02be394 c0127232 00000001 c02be394 00000001 c123e000 c0127331 c02be2e0 00000000 c123e249 0008e000 Call Trace: [<c013d38b>] [<c01271e7>] [<c0127232>] [<c0127331>] [<c0127396>] [<c01274ad>] [<c010553c>] Code: 89 11 89 46 30 89 40 04 8b 46 4c 85 c0 74 12 8b 40 14 85 c0
