I have an Asus P8B-M motherboard that has been in use for several years. It is now randomly stopping operation several hours after booting; as in just suddenly stopping all CPU operation. It is running a current Ubuntu server Linux. No hardware changes have been made to the system for months prior to this. Memory test did not uncover any errors. Reseated all the cables, memory, and two PCI cards.
The BIOS syslog has entries that show
Sensor Number: 0x17 Reserved or Unknown Event Description: Record Type 0x02, Assertion Event, Channel Number 0x 0.
It has some hex values displayed:
71 2 2 DE E7 CB 5A 88 0 4 DC 17 75 A0 4 0
Is there any way to know what that error means? I have been unable to find information about it by searching. The Linux logs do not show any unusual errors; they just stop at the moment the system locks up. The BIOS syslog entries do NOT show up EVERY time the system locks up, though.
