[Kernel panic - 6.9.1 cant complete parity checks!]

Following hard reboot i get a succesful (!) parity check msg

Unraid Parity sync / Data rebuild: 16-04-2021 18:55

Note the speed 'nan B/s' ?

[Kernel panic - 6.9.1 cant complete parity checks!]

system wont reboot, needs  a hard powerdown once locked up.

[System boots from 6.9.0 but wont reboot!]

Was there any 6.9.0 upgrade actions to do with this? My system has been rock solid for years, its only this latest upgrade that has broken it, cant be a coincidence., once i regress back to 6.8.3 its back to normal able to reboot from the main screen no problem. Any link to this other occurrence? What diagnostics are likely to be able to identify the problem here as everything works until i press 'reboot', the system goes down as expected, just doesnt return, needs a power off/on.

Thanks!

Joining the unraid 'me_too' on this one.

My system is Supermicro board, xeon 3460, stable for around three years across all upgrades. Since 6.7.2 upgrade i've experienced loss of webgui needing hard resets. Last couple of days, server has crashed while idle (??) and i'm unsure of how to catch the syslog in this event (tail??). I now have a screen and keyboard hooked up but what are the commands needed to allow me to monitor the syslog? I'm sure this will happen again. Parity check running. Next up is to double up on parity, maybe go back a release?
