problems with Sonnet Tempo ATA-100 - Is it supported?

[Kevin B. Hendricks]

Hi,

Just to be specific, here is the patch I applied to the pdc202xx.c driver
based on Promise's own code correction sent to the linux kernel mailing
list.

This fix is what got me past the hung partition table.

Ideas welcome.
