I can confirm (somewhat) similar issues with the newest Debian 11
(Bullseye) and Kernel 5.10 on HP Proliant DL380 G7 servers. Boot does
sometimes work, then it doesn't work (with a freeze caused by NMI), leading
to a very unstable OS.

After disabling hpwdt (module blacklist), the problems were gone. I
documented the troubleshooting and solution on my blog:

Ubuntu seems to have disabled/blacklisted the hpwdt module since 2015
already: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1432837
Maybe something Debian should also consider?
