AIC7899G + Driver works just fine (was: Remaining issues with install floppy)

["Marco Peereboom" <slash@peereboom.us>]

After 5 days of beating the snot of the 7899 driver I came to the conclusion
that it works like a champ.

I am using a 7899G which had a bunch of problems a few months ago. The
multiple disks per channel issue is definitively fixed. I ran 6 drives on
channel 0 and 14 on channel 1. The box is a Dell PowerEdge 2500 with an
external PowerVault 220S. I used a homegrown IO generating tool to beat on
the drives (I use this tool to validate drivers at work). Details on the
config are in my previous posting.

Does anyone care or want me to repeat this test with a 7892?

For now I am off to play with RAID frame :-)

Let me know,
/marco
