https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249369 Bug ID: 249369 Summary: device dtrace and device dtraceall are incompatible with options ZFS Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: Trond.Endrestol@ximalas.info I have a custom kernel which specifies device dtrace device dtraceall along with options ZFS While booting the custom kernel, amd64 r365792, I get this crash dump: Fatal trap 12: page fault while in kernel mode cpuid = 5; apic id = 0a fault virtual address = 0x7fffffff8 fault code = supervisor write data, page not present instruction pointer = 0x20:0xffffffff8081c16b stack pointer = 0x28:0xfffffe000dffeb00 frame pointer = 0x28:0xfffffe000dffeb80 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (dtrace_taskq) trap number = 12 panic: page fault cpuid = 5 time = 1 KDB: stack backtrace: db_trace_self_wrapper() at vpanic() at panic() at trap_fatal() at trap_pfault() at trap() at calltrap() at --- trap 0xc, rip = 0xffffffff8081c16b, rsp = 0xfffffe000dffeb00, rbp= 0xfffffe000dffeb80 --- osd_set_reserved() at taskqueue_thread_loop() at fork_exit() at fork_trampoline() at --- trap 0, rip = 0, rsp = 0, rbp = 0 --- KDB: enter: panic [ thread pid 0 tid 100109 ] Stopped at db> Note: The keyboard is unresponsive at this point. Is there a way to specify a dump device from loader(8)? Disabling DTrace in the kernel config, both device dtrace and device dtraceall, lets the kernel boot properly. Specifying dtraceall_load="YES" in /boot/loader.conf compensates for the missing in-kernel DTrace support. BTW, is there a way of compiling and linking the systrace_freebsd32 module as part of the monolithic kernel? -- You are receiving this mail because: You are the assignee for the bug.help
