The BIOS reports this as Intel Pentium 4 CPU 2.4 GHz

When booting the Alpine linux CD, the CPU info reported is: Family 15,
model 2, stepping 7
256 KB cache
address size 36 / 32

By looking here:
https://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_processors#Pentium_4

It should be a Northwood


I am not awayre of Linux explcitely removing support for such a CPU and
I am running Linux on older machines, like real 586-class. Maybe some
specifich Alpine configuration?

Some posts on the net suggest issues with overclocking or similar,
however this is a Laptop, not overclocked and it did run FreeBSD fine
for year, I recently switched to Alpine. I did not notice the "issue"
because I installed on another system and transderred the Hard Disk.

Also, the issue is a "soft lockup" so in theory it should also relieve,
but it does not, indiccating that perhaps something is stuck?
