Every 24 to 48 hours I get a hard crash on my Myth
Backend:
kernel: CPU 0: Machine Check Exception:
0000000000000004
kernel: Bank 4: b200000000070f0f Kernel panic: CPU context corrupt My reseach pointed to a likely hardware issue, so
one at a time I tried the following:
- swap RAM with a known "good" chip - swap RAM with a different known "good" chip - ran memtets86 for a week (no failures) - moved around the PCI cards - swapped video cards - tried different PVR500 cards - swapped CPUs - kernal updates to 2.6.12 After each change the system still crashed with the
exact same error. More research pointed to a potential issue with the
nVideo chipset and DMA. I then set the system to boot with no DMA and it
is rock solid. The only problem is that 3 or 4 PVR500 recordings and a
stream or two leave the system in a 50% cpu wait state due to the slow
disk.
I'm having a hard time believing there is a DMA
issue with the nVideo chipset and there is virtually no discussion of it, so I
assume it's something hardware related to the disk.
Next I'm planning to pull the CDROM and swap the
IDE cables. Does anyone have other ideas I should try? I've been
holding off on:
- a power supply swap since I don't have a big enough spare and would hate to spend the money for a "test". - drive swap since it will be a pain - motherboard swap since it will be an expensive test BTW, it is an ABIT NF8 motherboard that I am
otherwise very happyy with.
Thanks,
Todd |
