The last working kernel is 4.12.14-lp150.12.16-default
Comment 1 Manfred Härtel 2018-10-29 15:52:54 UTC 
I see the same problems on a computer with both kernels, Dom0 and DomU, at 4.12.14-lp150.12.22-default . Downgrading the DomU to 4.12.14-lp150.12.16-default seems to avoid the problem here too.

Comparing the sources, there was some rework of the persistent grant handling in xen-blkfront.c in between.
Comment 2 Takashi Iwai 2018-10-31 11:27:43 UTC 
Could you test the latest kernel in OBS Kernel:openSUSE-15.0 repo?
Comment 3 Manfred Härtel 2018-10-31 17:25:26 UTC 
I installed the kernel from the Kernel:openSUSE-15.0 repo and had no crashes up to now.

It seems as if the problem is fixed!
Comment 4 Olivier Nicolas 2018-10-31 20:47:25 UTC 
Running 4.12.14-lp150.154.gd809a9c-default for a few hours without problem where previous kernels crash after a few minutes.
Comment 5 Takashi Iwai 2018-11-01 18:53:40 UTC 
OK, good to hear.  Then it must be the issue we've already addressed for SLE15 (but missed in Leap 15.0 by some reason).

Now submitted for the next update (MR#645932).
Until released, just keep your working kernel or OBS Kernel:openSUSE-15.0 one.
Thanks!

*** Bug 1115383 has been marked as a duplicate of this bug. ***
Comment 8 Olivier Nicolas 2018-11-10 15:50:23 UTC 
Running DomU 4.12.14-lp150.12.25-default without problem, Dom0 is still running 4.12.14-lp150.12.22-default.
