Diagnosis tool for broken hardware?
One of my laptops where Debian Penguin lives has constant problems with:
1. sata disk parity error
2. dead eth0, -- cannot reactivate without reboot NETDEV WATCHDOG can detect.
3. ACPI error message, not installed handle --- and when battery goes low, sudden death without any warning.
These happen sporadic, disk may survive several weeks, may die twice a day, also eth0.
I have two other happy Penguins, and have had three more in the past (they died in one reason and another) The one I have trouble is less than 6 month old, and once sent back to manufacturer and came back with new disk drive.
I tried several different kernels (versions and options), but situation is more or less same.
I also reinstalled original wiErDOU OS, out of box state, and disk and/or eth0 dies also.
I somewhat suspect hardware (or logic board) problem, but I do not have any method to either prove or disprove.. and pinpoint
Can anybody recommend good tools? I tried to surf web, but maybe I did not use correct keywords, I had either too many or nothing useful...
