I'll respin the patch and rebuild a kernel...

Yet another test kernel is being built in OBS home:tiwai:bsc1173860-3 repo, will appear later at:

http://download.opensuse.org/repositories/home:/tiwai:/bsc1173860-3/standard...

Fingers crossed.

This one works:

localhost:~ # lvcreate -m 1 -n m_vol -l 10 system Logical volume "m_vol" created. localhost:~ # uname -a Linux localhost 5.3.18-1.g119f164-default #1 SMP Thu Jul 9 15:22:58 UTC 2020 (119f164) x86_64 x86_64 x86_64 GNU/Linux localhost:~ #

NO crash. Looks like you found the issue.

Thanks. So it seems to be the NULL mddev->gendisk, indeed. FYI, Jeff, my fix branch is found in users/tiwai/SLE15-SP2/md-fix. -- You are receiving this mail because: You are on the CC list for the bug.
