I'm seeing a panic during install during the zfs probing on the 14-CURRENT 20230504 amd64 snapshot on a PowerEdge R7525 dual-EPYC system. I haven't submitted a bug report for a while, so let me know what other information is needed. Unfortunately the stack backtrace looks useless: panic: mtx_lock() of spin mutex (null) @ /usr/src/sys/kern/kern_clock.c:269 cpuid = 67 time = 1683225642 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe037aa72db0 vpanic() at vpanic+0x152/frame 0xfffffe037aa72e00 panic() at panic+0x43/frame 0xfffffe037aa72e60 __mtx_lock_flags() at __mtx_lock_flags+0x13b/frame 0xfffffe037aa72eb0 deadlkres() at deadlkres+0xef/frame 0xfffffe037aa72ef0 fork_exit() at fork_exit+0x80/frame 0xfffffe037aa72f30 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe037aa72f30 --- trap 0, rip = 0, rsp = 0, rbp = 0 --- KDB: enter: panic [ thread pid 0 tid 101238 ] Stopped at kdb_enter+0x32: movq $0,0xddd833(%rip) db> Start of dmesg: FreeBSD 14.0-CURRENT #0 main-n262746-4194bbb34c60: Thu May 4 08:05:46 UTC 2023 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 FreeBSD clang version 15.0.7 (https://github.com/llvm/llvm-project.git llvmorg-15.0.7-0-g8dfdcc7b7bf6) WARNING: WITNESS option enabled, expect reduced performance.
