Tumbleweed Build 20211110 kernel 5.14.14-2-default (2b5383f) (but it might have been failing in 5.13 and older kernels) https://openqa.opensuse.org/tests/2029105/file/serial0.txt Prints really long stack trace, which begins:
[ 5211.445898][ C0] sysrq: Show State [ 5211.446508][ C0] task:systemd state:S stack: 0 pid: 1 ppid: 0 flags:0x00000000
The dumps are reported because someone (the VM monitor, I suppose) pressed sysrq-t. The problem is in the test scripts. Either the test didn't finish or it finished and noone noticed. Anyway, does it still happen? If so, the tests need to be investigated, it's not a kernel fault. Note also: NFS: state manager: check lease failed on NFSv4 server 10.0.0.2 with error 13 This is permission denied. -- You are receiving this mail because: You are the assignee for the bug.
