Created attachment 163896 [details] core.txt.0 Fatal trap 12: page fault while in kernel mode cpuid = 2; apic id = 04 fault virtual address = 0x18 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80904e29 stack pointer = 0x28:0xfffffe0114b71830 frame pointer = 0x28:0xfffffe0114b71a20 code segment = base rx0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 1791 (kdeinit4) trap number = 12 panic: page fault cpuid = 2 KDB: stack backtrace: #0 0xffffffff80983060 at kdb_backtrace+0x60 #1 0xffffffff80946b46 at vpanic+0x126 #2 0xffffffff80946a13 at panic+0x43 #3 0xffffffff80d498db at trap_fatal+0x36b #4 0xffffffff80d49bdd at trap_pfault+0x2ed #5 0xffffffff80d4927a at trap+0x47a #6 0xffffffff80d2f282 at calltrap+0x8 #7 0xffffffff8090479a at sys_kevent+0x12a #8 0xffffffff80d4a2af at amd64_syscall+0x40f #9 0xffffffff80d2f56b at Xfast_syscall+0xfb
I suspect the issue is just the same as in bug #234561 (already fixed in base r340734); can you reproduce the panic with recent base / kernel?
(In reply to Andriy Voskoboinyk from comment #1) I am on 12.0-RELEASE-p3 now. Everything is working ok. I can't reproduce the bug. Thank you
(In reply to Ludger Bolmerg from comment #2) Great, thanks for fast reply.
