Probably those sched/fair patches.
Yes, after bisecting it turned out to be sched-fair-fix-eevdf-entity-placement-bug-causing-sc.patch
Taking 6.12.77-rc1 and reverting both of the sched-fair patches results in a working kernel that boots consistently (which I am using now to send this email).
Confirmed on RISC-V. Reverting "sched/fair: Fix lag clamp" commit b547745a2c78fd1cc1fdc6a0d1b05c884c05cec2 and "sched/fair: Fix EEVDF entity placement bug causing scheduling lag" commit f9891a33ba67ce40e5a17023d2f3a5e2b7d72ffd resolves the issue.
