I've seen this too and documented my findings here: https://www.claudiokuenzler.com/blog/1125/debian-11-bullseye-boot-freeze-kernel-panic-hp-proliant-dl380 (reason is the hpwdt module) This bug is most likely a duplicate of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=898336 where the same NMI's are reported with Kernel 4.16 but with Kernel 5.10 the boot issues/crashes seem to be even worse. Maintainers, please consider disabling (blacklisting) the hpwdt module by default (same as Ubuntu). If anyone REALLY needs it, it can be manually enabled.

And with some debug, I find the problem is due to CONFIG_INTEL_IOMMU_DEFAULT_ON=y So, as a workaround, we can use intel_iommu=off kernel option.
