Hello!
Currently testing the new Bullseye release (using firmware-bullseye-DI-rc2-amd64-netinst.iso) and see a strange phenomenon on a HP Proliant DL380 G7 server.
During boot, the following messages show up in the console:
[63.063844] pcc_cpufreq_init: Too many CPUs, dynamic performance scaling disabled
[63.063895] pcc_cpufreq_init: Try to enable another scaling driver through BIOS settings
[63.063943] pcc_cpufreq_init: and complain to the system vendor
According to Andreas Herrmann, the settings can be defined in the HP server BIOS:
Power Management -> Advanced Power Options -> Collaborative Power Control = enabled
This is active (is the default I believe). The Power Regulator is set to "Dynamic Power Savings Mode".
After these messages show up on the console, no login prompt appears. No network started. The server seems frozen - doesn't even react to CTRL+ALT+DEL on the console anymore. Not sure if this is caused by cpufreq or something else though.
This boot problem happened on 2 out of 3 server boots.
Is this a bug in Bullseye?
thx for any hints.
