Shortly after updating my file server to the latest 7.0_STABLE: NetBSD yggdrasil.technoskunk.fur 7.0_STABLE NetBSD 7.0_STABLE (YGGDRASIL) #120: Fri Nov 6 08:52:21 CST 2015 sy...@yggdrasil.technoskunk.fur:/r0/build/netbsd-7/obj/amd64/sys/arch/amd64/compile/YGGDRASIL amd64
the machine panicked. Upon reboot, the saved crash dump showed: $ crash -M netbsd.2.core -N netbsd.2 Crash version 7.0_STABLE, image version 7.0_STABLE. System panicked: trap Backtrace from time of crash is available. crash> bt _KERNEL_OPT_NAGR() at 0 _KERNEL_OPT_NAGR() at 0 vpanic() at vpanic+0x145 snprintf() at snprintf startlwp() at startlwp calltrap() at calltrap+0x11 VOP_PUTPAGES() at VOP_PUTPAGES+0x3a uvm_pageout() at uvm_pageout+0x2f1 crash> The machine was building a -current release at the time as well as serving the various src/xsrc/pkgsrc trees to two NFS clients building -current for other architectures. Also serving my home directory to a third client. The "_KERNEL_OPT_NAGR()" statements are puzzling. They would appear to refer to the "agr" link-aggregation pseudo-device, but the running kernel omits that device, including GENERIC, then using "no pseudo-device agr". I don't know if I can repeat it, but if it happens again, I'll make note of it. Anything else to look at in the crashdump? -- |/"\ John D.
