Hello,
I have installed NetBSD 6 (from CVS) on a Blade 2000 (SMP).
Sometimes,
system panics with :
"cpu0; ipi_send: couldn't send ipi tu UPAID 1 (tried 1000 times)".
Graphic adapter is a well known Creator 3D (ffb2+ if I remember),
but
this adapter is in UPAID 0. I don't understand why kernel try to
send
ipi to a empty slot. Any explanation ?
Can you paste the cpu attach lines from dmesg?
The cpus are identified by UPA id numbers, which is often not
identical to
the (order of attachment) number identifying the cpu for autconf,
i.e. cpu0
might have UPA ID 2 and cpu1 UPA ID 0.
