https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D274954 Bug ID: 274954 Summary: Kernel with INVARARIANTS panic when drm module loaded Product: Base System Version: 15.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: oleg.nauman@gmail.com Kernel with INVARIANTS panic when entering multiuser mode after sucessful system boot. It happens when I boot CURRENT kernel with INVARIANTS and drm module loaded ( drm-515-kmod-5.15.118_1 to be precise ). kernel and drm mod= ule are in sync. ----------------------------- FreeBSD moonset.home 15.0-CURRENT FreeBSD 15.0-CURRENT #3 main-n266267- e116e040f309: Sun Nov 5 10:00:51 EET 2023 root@moonset.home:/usr/obj/u= sr/ src/amd64.amd64/sys/moonset amd64 panic: sleepq_add: td 0xfffff8000203c000 to sleep on wchan 0xfffff800021d86= 48 with sleeping prohibited ...............
