[Bug 1827822] Re: kernel null pointer dereference

2019-10-07 Thread Darin 
Thanks for the response. What version of memtest did you run and how
long did you have to run it? You ended up having a bad stick of ram? Did
you have to test each one individually?

I just built this PC a few months ago and after building ran memtest for
a whole day without problem but maybe I'll have to try it again. My log
mentions amdgpu after the crash each time so it may be a problem with
the graphics card or amdgpu driver. There are a few similar bug posts
I've found indicating it might be an amdgpu driver issue. Here are a
few.

[Bug 1827822] Re: kernel null pointer dereference

2019-10-05 Thread Ken Corbin 
A month or so after reporting this, amid a frustrating series of
unpredictable lockups, I figured out how to run memtest which indicated
I had a bad memory card.  Since replacing it, I have had no further
problems.

I just had this happen to me. I'll attach the relevant part of the
syslog. If there's any more info that I could give that would help just
let me know. Using Kernel 5.3.0-10-generic from Eoan.

[Bug 1827822] Re: kernel null pointer dereference

2019-05-17 Thread Ken Corbin 
No I can not reproduce this.  Which is not that surprising, deep kernel
bugs are unlikely to be correlated with anything the user is doing at
the UI level.  System is still crashing sporadically, they do not occur
on any of my other systems, nor did they happen on this system before a
certain date, which inclines me to claim that they were not happening
with older kernels.

It did lock up again this morning.  Unfortunately the last 5 minutes of
the syslog file were corrupted and contained no useful information, so I
could not tell you if it was the same problem or not.

Hello,
can this issue be reproduced? How to trigger it?

Also, do you have this issue with an older Bionic kernel? (like 4.15.0-47)
Thanks.
