Dear colleagues, my backup server after updrade to frest stable/10 start panicing on heavy disk load like rsync at FreeBSD whale.rinet.ru 10.1-STABLE FreeBSD 10.1-STABLE #195 r274646: Tue Nov 18 12:15:24 MSK 2014 marck@castor.rinet.ru:/usr/obj/FreeBSD/pristine/src.10/sys/GENERIC amd64 panic: vm_fault: fault on nofault entry, addr: fffffe001805b000 cpuid = 0 KDB: stack backtrace: #0 0xffffffff80964fa0 at kdb_backtrace+0x60 #1 0xffffffff8092a085 at panic+0x155 #2 0xffffffff80ba168e at vm_fault_hold+0x1b6e #3 0xffffffff80b9fad7 at vm_fault+0x77 #4 0xffffffff80d2861c at trap_pfault+0x19c #5 0xffffffff80d27dea at trap+0x47a #6 0xffffffff80d0db92 at calltrap+0x8 #7 0xffffffff819df8ee at fzap_cursor_retrieve+0x16e #8 0xffffffff819e4c97 at zap_cursor_retrieve+0x1f7 #9 0xffffffff81a1fed6 at zfs_freebsd_readdir+0x426 #10 0xffffffff80e456b7 at VOP_READDIR_APV+0xa7 #11 0xffffffff809d68cc at kern_getdirentries+0x21c #12 0xffffffff809d6688 at sys_getdirentries+0x28 #13 0xffffffff80d28da1 at amd64_syscall+0x351 #14 0xffffffff80d0de7b at Xfast_syscall+0xfb Uptime: 1m51s Unfortunately it's ZFS only, so I have no space to white panic dump. I'm now trying to rebuild kernel with debugger turned on, as luckily I have working console@SOL... Any preliminary hints? -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
