Comment 2 Yanko Kaneti 2018-12-27 15:35:03 UTC
I can confirm the fix.

After applying 77acd1cd912987ffd62dad6a09275a1fb406f0c2 on top of linus tip  shell is stable, so far.

Thanks

I am also confirm that patch https://cgit.freedesktop.org/~agd5f/linux/patch/?id=77acd1cd912987ffd62dad6a09275a1fb406f0c2 fix this.
Comment 4 Yanko Kaneti 2019-01-07 07:30:05 UTC
The fix landed on Linus's tree yesterday , so closing
Comment 5 mikhail.v.gavrilov 2019-01-07 08:47:24 UTC

FWIW I've been running linus rc1+ and after that 5.0.0-0.rc1.git0.1.fc30.x86_64 without having any issues with my Polaris11, where previously the bug triggered in the first minute of use.

This looks like a separate issue, see bug 109234 and follow-ups to https://lists.freedesktop.org/archives/dri-devel/2019-January/202909.html .
