Blade 2000 stability issue

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

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 ?

Regards,

JKB
