For a month or so I've been seeing panics when doing bulk builds
on sparc64. It is always of the form seen in the subject. I'm attaching
a representative dmesg of the LDOMs that make up the cluster along
with traces I've done of the crashes. I often had trouble tracing as
switching to another cpu would just hang. Thanks to jca for pointing
out that not all cpus may be in the stopped state and pointing out
how to avoid those. (Thus better traces as time goes on).
It does not seem to be a hardware issue since it has happened on
the LDOMs on multiple T4-1s.
