I saw no reply, neither I had one from the author (which, I assume, is busy 
enough). Anyone know if there has been progress recently? The driver on 
dialnet doesn't seem updated.


Here is my problem, as reported to the author. It's almost the same as Tom 
Pinkl's one:


I want to report my experience with your new driver, 5.0.14 (shipped with 
Linux 2.0.34) and 5.0.19 (taken from your FTP server, ftp.dialnet.net). Before 
your patches, I used Linux 2.0.33 with the "old" aic7xxx driver. It seems 
everything was fine (I just had a problem with the CD writer Ricoh but I'm not 
sure it was aic7xxx-related).

In 2.0.34, it no longer works: when the kernel boots, it initializes the 
driver (it's in the kernel, not in a module), prints the two hard disks and 
then has problems. Sometimes, it boots but do not detect my two CD-ROM drives. 
Sometimes, it loops forever, spitting out SCSI messages.

I tried:

- patching the 2.0.34 kernel from 5.0.14 to 5.0.19: same thing.
- compiling with egcs and gcc: same thing.
- retro-patching 2.0.34 with the driver from 2.0.33: it works fine, so I 
assume the problem is in the driver, not in 2.0.34.

My configuration: Dell Optiplex Gxa, Pentium Pro, Adaptec Ultra card. Two hard 
disks, one CD-ROM reader (NEC), one CD writer (Ricoh). Here are the messages 
from the old driver (I cannot easily get the messages from the new driver 
since it doesn't boot most of the time):

>From the new driver, I get the following messages (sorry, they are not 
litteral, but copied from a paper):

[Hard disks detected, just as above.]

Aborting command due to timeout
 [And sometimes: ] Bad scbptr 16 during SELTO


Should I post on the AIC7XXX mailing list? I'm of course ready to perform more 
experiments if it can help you.
