Subject: sparc32 SMP debugging advice needed
Date: Fri, 23 Mar 2007 21:42:14 +0000 [thread overview]
Message-ID: <460449B6.7010308@earthlink.net> (raw)
I'm trying to get a git rc4 SMP kernel working on an ss20 and am running
into a few problems.
An SMP kernel boots and runs fine using debian etch and a single
CPU. However I do get this in kern.log:
Mar 23 10:59:53 ss20 kernel: Kernel command line: root=/dev/sda2 ro
Mar 23 10:59:53 ss20 kernel: PID hash table entries: 1024 (order: 10,
4096 bytes)
Mar 23 10:59:53 ss20 kernel: start_kernel(): bug: interrupts were
enabled early
Mar 23 10:59:53 ss20 kernel: Console: colour dummy device 80x25
It looks like something similar was fixed a while back on sparc64 but
I don't know if this is related. I'm recompiling a kernel with more
debugging turned on to see what happens.
I get a hang when booting the same kernel with 2 CPUs at:
Begin: Loading essential drivers... ...
Nothing interesting before that.
Any advice on how to approach fixing these issues? I can test patches.
