gang,
I got the following when manually creating a kernel core dump from
within DDB:
\begin{console}
FreeBSD/sparc64 (u5.pn.xcllnt.net) (ttyu1)
login: ~KDB: enter: Break sequence on console
[thread pid 23 tid 100011 ]
Stopped at kdb_enter+0x3c: ta %xcc, 1
db> call doadump
Dumping 256 MB (1 chunks)
chunk at 0: 268435456 bytes ... ok
Dump complete
= 0xa
db> c
Interrupt storm detected on "vec2016: atapci0"; throttling interrupt
source
FreeBSD/sparc64 (u5.pn.xcllnt.net) (ttyu1)
login:
\end{console}
I don't get the interrupt storm triggered on any of the other platforms
I can test. It may not be worth looking into. On the other hand, it may
be symptomatic for more fundamental problems.
Details about the machine can be found here:
