Re: mcp51 chipset: usb not working with "noapic" ... system freezes without "noapic"
Note that I seem to have found the correct combination of kernel parameters to get things stable for the Compaq Presario V6017AU that have this nVidia mcp51 chipset. It is simply "pci=msi,mmconf". No need for "noapic".
The bugzilla entry that I mentioned in the OP have also been updated.
