PC crashes

Postby RHF91 » 2018/04/21 21:16:10

dear gentlemen
I am just starting into Linux, sorry for my ignorance, many thanks in advance for your help.

My PC is brand new, and I just added/installed Thunderbird on top of the Gnome release.
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-693.21.1.el7.x86_64
Architecture: x86-64

My problem is that it crashes, generally when it is running idle.
The error message (even before I installed TB) I got is :
WARNING: CPU: 0 PID: 0 at net /sched/sch_generic.c300 dev_watchdog+0x242/0x250-abort_
this problem should not be reported (it is likely a known problem). A Kernel problem occurred , but your kernel has been tainted (flags : GW). Kernel maintainers are unable to diagnose tainted reports.

I have been looking around the web to try to find a reason/explanation for the problem.
I trend to think that it is due to my graphic card (AMD R5230-SL-2GD3-L) because on the desktop screen, I have from time to time a white stripe. My screen is ok (I know because I still use it in this transition period, under Windows OS, with no problem).
On top of what I read on some sites.
But I am not sure at all.

I tried to find out whether the driver of the graphic card is up to date, but did not find a clear way.
I found where apparently I could have the last version, but I am not very used in downloading/installing drivers with Linux.
I am afraid the situation would get worse !

I only managed to see the error message mentioned hereabove one time, and did not manage to find it through the terminal application.

Again thank you very much in advance for your help.

PC Crashes are a fact of life... unfortunately.

Troubleshooting them is a giant PITA. There are a couple of things you can try.

A good place to start is to check both /var/log/Xorg.0.log and /var/log/dmesg to see if there is something out of whack.

Code: Select all

 "from time to time a white stripe."


I've had this problem occur a few times. As crazy as this may sound try swapping out your SATA cable. For reasons unknown they sometimes go south, the fix is simply to swap them out for a new one.

Second try removing Thunderbird via yum remove... and reboot the machine. This will tell you if you have a software problem. You can always reinstall it to replicate the problem.

Third, if you have one laying about the place, try another graphics card. This will tell you if you have a hardware problem.

If the problem persists try downloading as clean copy of CentOS 7.4, check and make sure that the MD5sum or the equivalent matches, then do a reinstall. Your:

Code: Select all

WARNING: CPU: 0 PID: 0 at net /sched/sch_generic.c300 dev_watchdog+0x242/0x250-abort_
this problem should not be reported (it is likely a known problem). A Kernel problem occurred , but [b]your kernel has been tainted[/b] (flags : GW). Kernel maintainers are unable to diagnose tainted reports.


...Almost sounds like you *might* have a corrupted kernel.
