RE: BETA6.0 - AMD Opetron 6272 (16 core) multiprocessor config crashes


I have tried the latest HEAD kernel from yesterdays build and the server
crashed when I started scp'ing a file..

I can replicate this issue on all three of the new servers.. 

I am also using a LSI 2108 as the primary disk controller so not sure if
theres some irq clash.. however seems like disabling SMP seems to fix the
issue rightaway.. I was also able to build couple of custom kernel by
turning of SMP...

Can you try a HEAD kernel ? I've been playing with NetBSD on a 4-6282 system
and couldn't make the kernel crash ...
