commit e0eef3690dc66b3ecc6e0f1267f332403eb22bea upstream.
Confirming that this^ revert resolves the reported non-boot regression
System does boot cleanly; but, then REboots @ 60 seconds.
It's a known bug, with fix already in 5.13.9/stable:
Revert "watchdog: iTCO_wdt: Account for rebooting on second timeout" https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/c...
, causing TCO watchdog auto-reboot @ 60 secs.
Although particularly nasty on servers with /boot on RAID, breaking arrays if watchdog boots before arrays correctly assembled, iiuc, it's UN-related
With interim workaround
edit /etc/modprobe.d/blacklist.conf
- blacklist iTCO_wdt
- blacklist iTCO_vendor_support
for this second issue in place, 5.13.8 boots & appears stable.
I do not understand, am I missing something in the queue for the next 5.13 release that needs to be applied?
no.
just confirming this^ revert, landed in 5.13.8, _works_ to fix non-boot.
system _does_ bump into 60-sec REboot. wasn't sure it's related to this^ or not ...
the fix for this _next_ issue appears already in 5.13.9/stable (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/c...) The module blacklist workaround works for 5.13.8.
i.e., as it stands, 5.13.8 is usable (here), iff the iTCO mod blacklist workaround is applied. 5.13.9 is expected to resolved it.
