https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207998 Bug ID: 207998 Summary: Panic during boot on Sparc64 11-CURRENT (r296811) Product: Base System Version: 11.0-CURRENT Hardware: sparc64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: dal36@gmx.co.uk I'm experiencing a panic during boot on sparc64 11-CURRENT (r296811). This install was booting without problems on 11-CURRENT r296149, and booting the= old kernel avoids the panic. Update procedure was as described in the handbook (23.6 Rebuilding World). Whilst I'm not familiar with the Sparc64 source, t= he panic seems to be occurring around addition of nexus0 and I noticed that a change was commited to nexus-related code in r296250; could this be related? Boot messages as follows: Hit [Enter] to boot immediately, or any other key for command prompt. Booting [/boot/kernel/kernel]...=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20 jumping to kernel entry at 0xc00b0000.
