I have CCed some maintainers, hope they might have a look at it (sorry, didnt check any MLs).
My kern.log and kernel-config are attached.
I get oops in bind_cdev() called from thermal_cooling_device_register() on mmotm, I expect yours is the same (but bind_cdev inlined so it doesn't appear in the backtrace). This patch gets me booting (note it also fixes return to break to unlock the mutex), does it help you? Whether the root problem is elsewhere or not, I've no idea; but I see Dan already spotted other errors hereabouts - probably needs more thorough review.
Thanks, this patch fixes the bootup problem. Anyway, this new kernel is not running properly, I see hangings while doing my daily work.

I have CCed some maintainers, hope they might have a look at it (sorry, didnt check any MLs).
My kern.log and kernel-config are attached.
I get oops in bind_cdev() called from thermal_cooling_device_register() on mmotm, I expect yours is the same (but bind_cdev inlined so it doesn't appear in the backtrace). This patch gets me booting (note it also fixes return to break to unlock the mutex), does it help you? Whether the root problem is elsewhere or not, I've no idea; but I see Dan already spotted other errors hereabouts - probably needs more thorough review.

thanks for the fix, this patch looks good to me. could you please resend it in a proper format, say, with changelog and Singed-off-by, so that I can apply to my -next tree?
thanks, rui

I have CCed some maintainers, hope they might have a look at it (sorry, didnt check any MLs).
My kern.log and kernel-config are attached.
I get oops in bind_cdev() called from thermal_cooling_device_register() on mmotm, I expect yours is the same (but bind_cdev inlined so it doesn't appear in the backtrace). This patch gets me booting (note it also fixes return to break to unlock the mutex), does it help you? Whether the root problem is elsewhere or not, I've no idea; but I see Dan already spotted other errors hereabouts - probably needs more thorough review.

Shouldn't this be a 'continue' instead of the 'break' here ? With this change, I just sent a patch,
