https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D247443 Bug ID: 247443 Summary: panic at boot while loading radeonkms Product: Base System Version: 11.4-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: serpent7776@gmail.com Created attachment 215820 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D215820&action= =3Dedit output of `crashinfo kernel core` After upgrade from 11.3-RELEASE to 11.4-RELEASE FreeBSD panics at boot while loading radeon kms. I have Radeon HD 5450. drm packages installed: drm-fbsd11.2-kmod-4.11g20200420 drm-kmod-g20190710 build from ports I did try to rebuild drm-fbsd. booting into single user mode and kldload'ing radeonkms results in the same panic. Here's the backtrace at panic time: KDB: stack backtrace: #0 0xffffffff80b431b5 at kdb_backtrace+0x65 #1 0xffffffff80afd2be at vpanic+0x15e #2 0xffffffff80afd153 at panic+0x43 #3 0xffffffff80f75fc5 at trap_fatal+0x365 #4 0xffffffff80f76019 at trap_pfault+0x49 #5 0xffffffff80f756ce at trap+0x27e #6 0xffffffff80f5526f at calltrap+0x8 #7 0xffffffff825fde6c at reservation_object_wait_timeout_rcu+0x6c #8 0xffffffff8260f8f8 at ttm_bo_wait+0x48 #9 0xffffffff824dd09d at radeon_bo_move+0x2d #10 0xffffffff82610f4e at ttm_bo_handle_move_mem+0x1ce #11 0xffffffff8260de04 at ttm_bo_validate+0xd4 #12 0xffffffff8260e28a at ttm_bo_init+0x37a #13 0xffffffff824d14e1 at radeon_bo_create+0x1a1 #14 0xffffffff824dbc5f at radeon_ttm_init+0x21f #15 0xffffffff8245ffc3 at evergreen_init+0x103 #16 0xffffffff824b88f5 at radeon_device_init+0xd15 #17 0xffffffff824c9f2c at radeon_driver_load_kms+0x13c but when I did `kgdb kernel vmcore` and then `bt` I get #0 doadump () at pcpu.h:234 #1 0xffffffff80afcef5 in kern_reboot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:388 #2 0xffffffff80afd2f6 in vpanic (fmt=3D<value optimized out>, ap=3D<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:784 #3 0xffffffff80afd153 in panic (fmt=3D<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:715 #4 0xffffffff80f75fc5 in trap_fatal (frame=3D<value optimized out>, eva=3D= <value optimized out>) at /usr/src/sys/amd64/amd64/trap.c:899 #5 0xffffffff80f76019 in trap_pfault (frame=3D0xfffffe0352326f90, usermode= =3D0) at pcpu.h:234 #6 0xffffffff80f756ce in trap (frame=3D0xfffffe0352326f90) at /usr/src/sys/amd64/amd64/trap.c:438 #7 0xffffffff80f5526f in calltrap () at /usr/src/sys/amd64/amd64/exception.S:288 #8 0xffffffff825ee882 in linux_rcu_read_lock (type=3D<value optimized out>= ) at /usr/src/sys/compat/linuxkpi/common/src/linux_rcu.c:202 #9 0xffffffff825fde6c in reservation_object_wait_timeout_rcu () from /boot/modules/linuxkpi_gplv2.ko #10 0xffffffff8260f8f8 in ttm_bo_wait () from /boot/modules/ttm.ko #11 0xffffffff824dd09d in ??
