https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261284 Bug ID: 261284 Summary: bhyve emulation of 12.3 on 12.3 frequently crashes Product: Base System Version: 12.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: d8zNeCFG@aon.at Created attachment 231089 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D231089&action= =3Dedit core.txt.0, info.0 Scenario: - Host system (hal) recently updated from 12.2 to 12.3 (amd64) - Client system (v909) running 12.3 i386 off a ZFS volume - /usr/src and /usr/obj are on hal and reachable by the client via NFS - "cd /usr/src && make installkernel installworld DESTDIR=3D/usr/tmp/x ..." Result: - Normally, this setup works (mostly) o.k. - But with this boot of the host (hal), the client (v909) always crashes whenever doing the above install - Crash info attached Notes: - In 12.3 there seems to be a regression in bhyve because quite often clien= ts running 13.0 just stop in the boot process (zero CPU in the host). They hav= e to be killed using bhyvectl, and in most cases after a restart they boot norma= lly. This seems to indicate some uninitialized data affecting 13.0 clients (amd64 clients more than i386). - In the special case described in this PR, the 12.3 i386 client reliably crashes (I have tried it three times so far without rebooting the host). I = am fairly sure that once I reboot the host the problem will have gone away. Th= is again seems to indicate some uninitialized data affecting, in this case, a = 12.3 i386 client. - In 12.2 (host) there were basically no bhyve problems for both 12.2 and 1= 3.0 clients (amd64 and i386). Summary: There seems to be a regression in bhyve from 12.2 to 12.3, most li= kely with some uninitialized data structures, most likely in the host, but proba= bly also in the client. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
