http://bugzilla.opensuse.org/show_bug.cgi?id=973991 http://bugzilla.opensuse.org/show_bug.cgi?id=973991#c14 --- Comment #14 from Justin Bandholz --- I believe I have recreated a similar failure to what is described here during an installation of Tumbleweed or Leap in KVM virtual machine on a Tumbleweed or Leap 42.2 host. when CPU model is "host-model", installation fails when probing the storage system; looks like raid code bombs. when CPU model is "host-passthrough", everything works fine when CPU mode is "host-model" and you force off AVX, everything works fine <cpu mode='host-model'> <model fallback='allow'/> <feature policy='disable' name='avx'/> </cpu> The failures that Matthias reported seemed related to AVX and CRC processing. Attached screenshots of install hang and stacktrace as well as cpuinfo of host. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=973991 http://bugzilla.opensuse.org/show_bug.cgi?id=973991#c16 --- Comment #16 from Sebastian Parschauer --- Yep, the raid6_pq driver depends on avx to be available. This is why it fails in raid6_avx21_gen_syndrome(). If it depends on that CPU feature, then it should check during driver init if it is available first. If it is not available, then that driver should disable itself. The kernel command line option

modprobe.blacklist=raid6_pq

should be able to fix this if that driver is not needed. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=973991 http://bugzilla.opensuse.org/show_bug.cgi?id=973991#c18 --- Comment #18 from Justin Bandholz --- (In reply to Sebastian Parschauer from comment #17)

@Justin: Can you please retest with the kernel parameter from comment 16 entered at "Boot Options" at the "Installation" entry of the boot menu of the installation media?

Thanks in advance!

modprobe.blacklist=raid6_pq at boot did not fix the problem. Looks like the module is being pulled in as a dependency from another module (modules.dep confirms this). I added "install raid6_pq /bin/false" to /etc/modules.d/50-blacklist.conf and it seemed to do the trick; no fault. I've also included the runtime options that libvirt uses when it launches the vm. AVX and AVX2 are supported by the host cpu. 3178 ?
