https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194264 Bug ID: 194264 Summary: crash in unp_gc -> unp_accessable Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: avg@FreeBSD.org Created attachment 148131 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=148131&action=edit kgdb postmortem session First, I think that this panic could be related to a crash of chromium process that preceded it. Perhaps the crash triggered closing of sockets and that interacted badly with unp_gc code. Unread portion of the kernel message buffer: <6>pid 48502 (chrome), uid 1001: exited on signal 11 (core dumped) Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x100000021 fault code = supervisor read data, page not present ...
