Bug ID: 229167
Summary: [Hyper-V] [Jun 19, 2018] Recently FreeBSD VM panics
during boot-up, especially with Mellanox VF configured
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
People are seeing some different call-traces with FreeBSD 11.2 and/or the
latest CURRENT code recently and some call-traces are mentioned here :
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220453
#1: panic in namei():
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220453#c5
#2: panic in vmbus_msghc_exec():
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220453#c7
It's reported FreeBSD-12.0-CURRENT-amd64-20180618-r335317-disc1.iso also
reproduces this call-panic.
#3: No detailed call-trace. It looks the panic happens just after root is
mounted.:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220453#c14
But it looks I can't reproduce the issue any more, after I fresh-build a kernel
with the same version. Not sure if this is some kind of weird memory corruption
issue.
