I'm looking for help diagnosing an issue I'm having with Ubuntu 14.04 64bit.
I'm a relative newbie to all this, so I'm not really sure where to start.
Basically what happens is this:
computer boots up as normal
computer runs fine for a certain amount of time (normally an hour or so), whilst I work & browse the net.
Normally chrome (
Version 39.0.2138.3 dev (64-bit)
will crash, and all my other applications will freeze. This lasts about 30 seconds, then chrome will close and the other applications will be responsive again.P.S the fact it's normally google chrome is probably irrelevant - I have had this happen without opening chrome at all.
Other than using the applications I already have open, I can't do anything else. I can't open a new application (even using keyboard shortcuts), I can't close old ones, and I can't shut my computer down (the top right menu doesn't open and I can't get to terminal).
What I have attempted
Investigating with the virtual terminal
During the crash, I've tried to open a virtual terminal (ctrl-alt-f2
), but when I try to log in, I get the error:
[4210.959605] end_request: I/O error, dev sda, sector 5373856
gsmartcontrol disk scans on both SDD and HDD
Having seen the above, I thought my ssd (sda
) must be failing, so I downloaded and ran gsmartcontrol
and did the extended test on both my SSD and my HDD, and got no problems reported.
Memtest (Thanks @Rinzwind)
So far I've only had this running for 1.5 hours, which was enough to complete two test suites successfully with no failures. EDIT: Completed 9 hours last night with no errors.
I am not sure where to go from here though, are there some logs I can look into? Are my hard drives definitely okay if gsmartcontrol
tells me they are?
Thoughts & help much appreciated.
