been running @ACwifidude 's master git tree pulled Sat Aug 27, 2022; built using diffconfig-ath10k config (cp diffconfig-ath10k .config; make defconfig)
... had a several reboots under light load while I was periodically logging memory, CPU temp and top to another host ...
NO crash log - watchdog I guess ...
memory and temp look OK but the heaviest hitting task @50 % sys (i.e. sys task fully loading 1 core):
PID PPID USER STAT VSZ %VSZ %CPU COMMAND
13258 2 root RW 0 0% 50% [kworker/1:2+eve]
... and by the timestamps saved in syslog, it looks like this blocked for between 20 - 30 seconds ... I'm guessing the watchdog timeout is 30sec. CPU temp had risen by 4 - 5 degrees C too.
I'm going to drill down into this some more, patch the tree I have to dump which service/ISR task was being executed if I can ...
All hints accepted here - I haven't had to dig this deep into the kernel in a while and not one this new.
