Hi, I'm trying to run one of my older VM's and get the crash below in the VM when trying to boot... This happens both on an older BSD: FreeBSD 11.0-CURRENT (FREETEST) #1 r273066M: Sun Oct 19 00:59:06 CEST 2014 As well as on a very recent: FreeBSD 11.0-CURRENT (BHYVE00) #0 r274490M: Fri Nov 14 02:42:43 CET 2014 The older 10.0 VM's do boot normally Any suggestions on what this might be, and/or how to debug this.. --WjW DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 3 DHCPOFFER from 192.168.10.75 DHCPREQUEST on vtnet0 to 255.255.255.255 port 67 DHCPACK from 192.168.10.75 panic: ffs_write: type 0xfffff8000565dce8 0 (0,62) cpuid = 0 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00975374d0 kdb_backtrace() at kdb_backtrace+0x39/frame 0xfffffe0097537580 vpanic() at vpanic+0x126/frame 0xfffffe00975375c0 panic() at panic+0x43/frame 0xfffffe0097537620 ffs_write() at ffs_write+0x68b/frame 0xfffffe00975376c0 VOP_WRITE_APV() at VOP_WRITE_APV+0x16f/frame 0xfffffe00975377d0 vn_write() at vn_write+0x2f3/frame 0xfffffe0097537860 vn_io_fault() at vn_io_fault+0x17b/frame 0xfffffe00975379f0 dofilewrite() at dofilewrite+0x88/frame 0xfffffe0097537a40 kern_writev() at kern_writev+0x68/frame 0xfffffe0097537a90 sys_write() at sys_write+0x63/frame 0xfffffe0097537ae0 amd64_syscall() at amd64_syscall+0x25a/frame 0xfffffe0097537bf0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfffffe0097537bf0 --- syscall (4, FreeBSD ELF64, sys_write), rip = 0x800de9b4a, rsp = 0x7fffffffd4c8, rbp = 0x7fffffffd510 --- KDB: enter: panic [ thread pid 551 tid 100057 ] Stopped at kdb_enter+0x3e: movq $0,kdb_why
