The system's a new built-from-scratch, so I guess the problem could be any of the components. The system oopses *hard* under heavy load (make -j64 bzImage) pretty consistently. Hardware: 512mb PC133, single pIII/800EB on a dual Tyan S2507, Mylex 170LP (DAC960) RAID controller on 4 18gig disks. (Patched with Zubkoff's DAC960 patch, version 2.2.10 for kernel 2.2.18) I've swapped the RAM around and with some from a known-good system and I still get the crashes. They're generally so hard that I can't scroll back to copy anything from the screen. What I do get are lines like this one: [] [] [c011c1cc>]... repeating for at least a screen full, then: Code: 39 73 74 75 2d c7 43 50 11 00 00 00 ff 83 dc 04 00 00 a1 b0 One oops that wasn't hard enough to take out the entire system looked like this: kmem_free: Bad obj addr (objp=dbad0220, name=vm_area_struct) Unable to handle kernel NULL pointer dereference at virtual address 00000000 current->tss.cr3=00101000, %%crs = 00101000 *pde = 00000000 Any ideas?
