Hi! I had a panic on 8.99.37/amd64 (kernel from a couple hours ago) last night, usual setup: pbulk with 2 sandboxes on tmpfs, probably high memory pressure, perhaps one of the standard daily/weekly cronjobs running.
gdb does not give me a reasonable backtrace. Here's the panic message from syslog after reboot: Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NnOeTt bLsOdW:EpRoEoDl O_Ng rToRwAP+ 0ExXdI6T Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 65 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] pool_catchup() at WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 16 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWnEeRtEbDs dO:N pToRoAlP_ cEaXtIcTh u6p 0+ Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] 0x46 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 53 times Apr 22 03:17:47 yt /netbsd: [ 124[74 .1725487140.2785]8 1p0o2o8l]_ gWeAtR(NI)N Ga:t SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 10 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NnOTe tLbOsWdE:RpEoDo lO_Ng eTtRA+P0 xE9X7I8T Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 53 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNINGa: lSlPoLc bNuOfT( L)O WaEtR ED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 10 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXInTe t6b s0d Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] :allocbuf+0x11a Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 54 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] getblk(W)A RaNtI NG: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 10 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WA[R N1I2N4G7:4 .S7P5L8 1N0O2T8 ]L OnWeEtRbEsDd :OgNe tTbRlAkP +E0XxI1T8 46 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 61 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WAbRNiIoN_G:d oSrPeLa dN(O)T aLtOW ERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 14 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] netbsd:bio_doread+0x1b Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 51 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ObN rTeRaAdP( )E XaItT 6 0 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0 Apr 22 03:17:47 yt syslogd[197]: last message repeated 2 times Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] netbsd:bread+0x18 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] ffs_init_vnode() at netbsd:ffs_init_vnode+0x1c7 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] ffs_loadvnode() at netbsd:ffs_loadvnode+0xd3 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] vcache_get() at netbsd:vcache_get+0x5c5 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] ufs_lookup() at netbsd:ufs_lookup+0x1415 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] VOP_LOOKUP() at netbsd:VOP_LOOKUP+0xec Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] lookup_once() at netbsd:lookup_once+0x339 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] namei_tryemulroot() at netbsd:namei_tryemulroot+0xc51 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] namei() at netbsd:namei+0x65 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] fd_nameiat.isra.2() at netbsd:fd_nameiat.isra.2+0xd9 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] do_sys_statat() at netbsd:do_sys_statat+0x182 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] sys___lstat50() at netbsd:sys___lstat50+0x85 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] syscall() at netbsd:syscall+0x348 Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] --- syscall (number 441) --- Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] 79cafcd8f01a: Apr 22 03:17:47 yt /netbsd: [ 12474.7581028] cpu9: End traceback...
