Description Daniel Morris 2016-01-19 15:15:49 UTC

I've recently upgraded disks and updated to openSUSE's Tumbleweed rolling distribution. I've had several random hard locks and reboots. Please see the following bug report for steps tried so far and dmesg output:

https://bugzilla.opensuse.org/show_bug.cgi?id=960848

Previously the system ran happily with kernel 3.11.10 (openSUSE 13.1)

I haven't been doing anything particularly intensive, just basic browsing and the last time using management tools to add in a few fonts.

I have kernel dumps saved, is there anything I can try to capture more information?

Thanks,
 Daniel

Just to note, I haven't had a hard lock-up since adding the i915 options to the boot parameters of the kernel. 

As I'm still subscribed to the kernel:stable repo, I've had several new kernels since but I suppose those settings could be masking an upstream fix. For all kernels the machine has run happily for days until the next update was made, whereas before I could trigger things in a matter of hours. My current kernel version is 4.4.1-3.g2b16688-default.

From comment #19 in bug https://bugzilla.opensuse.org/show_bug.cgi?id=960848
Issue seems to be fixed with new upstream kernel, closing. Please reopen if there is anything left to do or the issue re-appears.

Sorry, I forgot to update the bug report.

Kernel was updated to 4.7.0-2 on 19 August and problems haven't reappeared so assume it really was fixed upstream. Thanks for your help.
