I'm running 2.6.11.8 on an server with two Promise Ultra133 TX2 (PDC20269)
PCI cards, same hardware revision (judging from stickers on the cards).
I'm using the CONFIG_BLK_DEV_PDC202XX_NEW driver.
Each card has two connected hard drives. Whenever I read from a disk
on one of the cards (e.g. using 'dd if=/dev/hdX of=/dev/null bs=1M'), and
at the same time read from a disk on the other card, there is heavy
software clock drift. It drifts about 2-5 seconds per minute.
This does not happen if I read from two drives connected on the same
card, or if I read from a drive connected to the motherboard IDE
(VIA vt8233a) and a drive on either of the Promise cards.
