Hi
anyone able to enlighten me as to what the following trap maybe caused by?
ram ?
Unable to handle kernel NULL pointer dereference at virtual address c000000d
current->tss.cr3 = 04654000, %cr3 = 04654000
*pde = 00102067
*pte = 00000000
Oops: 0000
CPU: 0
EIP: 0010:[<001468d4>]
EFLAGS: 00010246
eax: 00000000 ebx: 02b539e0 ecx: 042f2438 edx: 002870e8
esi: 042f24d4 edi: 00000000 ebp: 042f2414 esp: 0452fee8
ds: 0018 es: 0018 fs: 002b gs: 002b ss: 0018
it is inconsistent, sometimes the system will go 2 weeks till it occurs other
times it will do it within a day and the box does the same work day in day out
....
any clue appreciated....
