>Description:
Power Macintosh 7300 with 512MB RAM, Sonnet G3/500 and a Sonnet Tempo Trio ATA/133 USB/FireWire/ATA card using a Promise U133/ATA controller connected to an ATA/100 Western Digital 40GB drive. I have been unable to get the kernel to drive the controller at the full ATA/133 or even ATA/100; it persistently complains about a transfer error and downgrades to Ultra/33, at which point it appears to work normally but not at the full ATA speed capable. No SCSI drives except for the internal CD-ROM installed.

Relevant lines from kernel config file:
pciide* at pci? dev ? function ?
wd*     at pciide? channel ? drive ? flags 0x0000

dmesg with downgrading message follows:

>How-To-Repeat:
Boot the machine ;)
>Fix:
None yet. I tried changing flags on the drive, and adding a flags 0x0001 to the wd* line, and neither seemed to make a difference.
