Subjectmore strange things with aic7xxx (5.0.19 in 2.1.105)
	Well, I always thought computers were more or less machines, I mean,
when in the same conditions will do the same, but things are changing ...
I have patched the 2.1.105 with Doug Ledford 5.0.19 version of his
aic7xxx driver, and tachan!!, things work but only sometimes, and the
stranger thing is that it seems to depend of the order of the devices
ID's, I have a IBM 4.1 Gb disk, and a Pionner 24x SCSI and a Traxdata
4120 cdroms, the only way to make these works is to assign 0 to the IBM,
2 to the Pionner and 3 to Traxdata, (I've not test all variations (3^6
?), but I tested a lot, and the only way was that.

I have to specify no_reset and pci_parity (If I disable it in the
BIOS, the traxdata gets detected with the pionner id, and works fine but
I don't like so much risk :), and if I put the traxdata with an id lower
than the pionner's it will keep resetting the bus when detecting the
pionner. I'm really puzzled..., with 2.1.102 everything works fine,
doesn't matter the ids (as it should be?)

Here is my bootlog just to clear things, if you need more info I will
provide it.
