Re: sata_nv + SMP = broken?

Hello,
Yesterday I've tried launching various kernels on Ahtlon64 Dual-core
X2 3800+ with MSI Neo4 Platinum SLI motherboard.
The results were a total catastrophica failure. As soon as I enable
SMP in the kernel, the sata driver would randomly hang after a bit of
disk activity.
Whenever apic is enabled, the system won't even be able to boot up
completely, and will hang VERY soon. Whenever I disable apic, the
system is able to bootup, but when the software mirror that I use will
try to resync for 2-3-10 mins, it will throw up a message and freeze
again.
Whenever I disable apic AND lapic, the system is able to bootup AND
work, however after same 5-10 minutes it start spitting messages,
which are somewhat different thou and don't hang the system completely
but render it rather unusable anyway.
As soon as I disable SMP - everything works like a charm.
For what it's worth I too have seen this same problem. It happens when I
use the stock Fedora kernels but not my custom compiled kernel. I'm not
sure what I compiled differently but at the time I thought that
something in the new kernel fixed it.
I too am running an Athlon X2 using sata_nv. I have an ASUS motherboard.
But what I noticed was that the problem went away if I used 2 gigs of
ram instead of 4 gigs. When you use the whole 4 gigs there is some
memory mapping going on and I thought perhaps the problem was related to
the sata_nv not liking the memory mapped over the 4gig barrier. I did
not try disabling SMP.
