I have had problems with this chipset: 0000:00:0f.0 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06) When I first bought my board (MSI KT7) I had problems when large amounts of data went across the PCI bus. Check syslog for messages like 'spurious interrupt'. If that is the case see if there is a BIOS update. Do you know if you have the 'B' rev of the VIA southbridge? If you have the 'A' rev, there is a known bug. torleiv what you said > Hi, > > Just thought I'd mine the collective consciousness and see if anyone has > been having the same trouble I'm experiencing.
