Build results: total: 159 pass: 159 fail: 0 Qemu test results: total: 485 pass: 484 fail: 1 Failed tests: openrisc:or1ksim_defconfig
The openrisc failure is a soft lockup during restart. I only recently enabled the soft lockup detector, so this is probably either a false positive or not a new problem. I'll try to track it down, but it is not a concern for now.

Hi Guenter,
If you need help let me know, just let me know how to reproduce it. I am currently working on some qemu patches to convert qemu to multithread-tcg. I have fixed some lockup issues, but there are still some cases we get soft lockups.
If you have any details I can see if it's a similar issue.

All I can say is that it happens with qemu 7.0, it happens more or less randomly with all kernel versions as far as I can see, and it isn't a real lockup but something wrong with time management. The lockup is reported almost immediately on shutdown. It reports something like
reboot: Restarting system watchdog: BUG: soft lockup - CPU#0 stuck for 371s! [init:225] Modules linked in: CPU: 0 PID: 225 Comm: init Not tainted 6.0.0-rc1-00303-g963a70bee588 #1
but it doesn't really wait for that much time; the message is seen almost immediately. I don't do anything special, just boot the openrisc emulation and restart. I have the following options enabled.
CONFIG_LOCKUP_DETECTOR CONFIG_SOFTLOCKUP_DETECTOR CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC CONFIG_DETECT_HUNG_TASK CONFIG_BOOTPARAM_HUNG_TASK_PANIC
The problem is not seen without those options.
