Ultra100 controller works well, but I have had problems with some drives.

The card has been successfully used with Maxtor 30 & 100 GIG drives and IBM 60gig drives.

The card had troubles with Seagate 20 & 30 gig drives and Quantum Fireball drives. The problems were always random lockups of the entire OS. The lockups could be reproduced with a sector scan of the entire disk.

I've had similar problems and I think I may have found part of the problem. Somewhere on LQ there was a thread about power supplies which specifically mentioned that some PSUs can't deliver enough jam on the +12V bus. This can occur when there are several drives attached. I have noted that on a P4-1.8G we snuck around the problem by removing the ever-so-power-hungry Radeon AGP card and replaced it with a generic GeForce card.

I have never had a problem with this card using a bunch of different drives from IBM 13GB to a WD 150GB. Only problems I ever had were back in the late 2.2/early 2.4 kernel days when I had to specify the IDE addresses to the kernel to get it to recognize the disks. This was a pain but once I figured out what it was looking for it worked just fine.

I have a newer revision, the chipset reads 20286. For the Debain flavour I use (woody 3.0rc2 bf24, 2.4-18 kernel) this seems to be a problem, although I haven't figured it out completely yet. Will get back.

This device gives me problems on a Digital Alpha (PWS 433au). When dma is enabled it gives a lot of status errors, and data corruption. In PIO mode everything is fine (but terribly slow). Googling for mailinglists seems to indicate this is common behaviour on Alpha.
