[LUG]Re: Possible hardware failure - how to diagnose?

 

Dear Giles,

Many thanks for the suggestion. I have bought a can of compressed air so
I shall try that and let you know how it goes. Should I use it on the
SATA connectors too? I was able to get a glimpse of some IO-related
errors when Linux was starting that might perhaps be related to this
issue; here they are from dmesg:

There's another thing that is interesting - I came to my computer just
before writing this email to discover it locked up again, and the magic
Alt-SysRq code for 'reboot' actually worked! So maybe it is not
completely irresponsive after all.

Best wishes,

Sebastian
