Hello,
I bought just a new AMD64 system with an NForce 3 based mainboard (MSI
K8N Neo2 Platinum).
When I use the latest kernel from Andrew (2.6.9-rc2-mm3) on boot it
sometimes hung on boot and the reset state of system is wrong so a have
to power of the system until usb will work again..at probing the usb
devices (OHCI,EHCI). Also the system runs really slow and some tasks
starts and the system hungs. I also tried staircase patches and
voluntary-preemption but they also wont help.
Any suggestion or hints how to fix that behavior?
Thanks in advance

Send in your .config, lspci and dmesg to start off with.

There's a known problem with NForce2 and NForce3 chipsets that affects
at least IDE interrupt handling, the effect being that the system hangs
if there's "too much" disk activity. I've verified that this occurs
with 2.6.8.1, but haven't tried more recent snapshots.
The symptom is that the system hangs hard during boot.
A tolerable workaround appears to be to drop the IDE UDMA level down to
3 using hdparm. If you're using a Fedora Core distro and edit /etc/
sysconfig/harddisks to do this, it gets set up early enough during boot
that the system rarely hangs.
I haven't had time to look into this deeper, but I did file a bug
against it: http://bugzilla.kernel.org/show_bug.cgi?id=3398
It should probably be owned by Jens, since it seems to be IDE-specific,
but Andi has it for now.
