Southbridge Issues (SB7x0)
Most OSes require patches in order to work reliably.
- Windows platform:
- Microsoft KB982091
- Microsoft KB956871
- Microsoft KB953689
- Linux platform:
- HPET operation with MSI causes LPC DMA corruption on devices using LPC DMA (floppy, parallel port, serial port in FIR mode) because MSI requests are misinterpreted as DMA cycles by the broken LPC controller
- USB freeze when multiple devices are connected through hub (related to AMD Product Advisory PA_SB700AK1)
- Erratic behaviour of the HPET when Spread Spectrum is enabled (related to AMD Product Advisory PA_SB700AG2)
- Disabling legacy interrupts for SATA disables MSI too
- SATA soft reset fails when PMP is enabled and attached devices will not be detected
- SATA internal errors are ignored because the controller will set Serial ATA port Error when it should not

Famous quotes containing the word issues:
“Your toddler will be “good” if he feels like doing what you happen to want him to do and does not happen to feel like doing anything you would dislike. With a little cleverness you can organize life as a whole, and issues in particular, so that you both want the same thing most of the time.”
—Penelope Leach (20th century)
