Subject: [2.6.22-rc6] NForce4 soft and hard resetting ports and exceptions

I tried Linux 2.6.22-rc6 on my machine with an Asus A8N-SlI Deluxe
motherboard (NForce 4 chipset).

When booting, the system hangs for a long time, but it continues after a
long wait. I found these kind of errors in the logs afterwards:

With Linux 2.6.21 this did not happen.

After disabling hddtemp and smartd services, these errors do not happen
anymore.

This was a bug in smartmontools. It is fixed in CVS and should be in
the next released version.
