My HP ProBook 450 G7 8VU55ES randomly hangs on boot. Not always, perhaps in 10-20 % of all cases.
Then I get this dmesg:

my kernel config:

Could'nt find anything, what helped.
Any ideas?
Thanx in advance!

Try with
gentoo-kernel-bin
and if it is ok then reconfigure the problematic kernel.

JFTR: I've set CONFIG_RCU_CPU_STALL_TIMEOUT to 5, which seems to work until now...

stuck while booting this morning. :-(
