Uh Oh...
Is this a fix for the problems I reported back in June to LKML and to Pam Delaney?
On June, 12th, I sent a mail to Pam reporting system freezes I had on an ASUS AP 1700-S5 server with onboard 53C1030 controller. In this mail I speculated about the possibility of a mixed device configuration beeing the source of the problem:
[...] Another idea: is it possible that the SCSI controller has problems with U160 and U320 SCSI disks mixed together on the same bus? As far as I know there shouldn't be a problem with this combination, but who knows?
I always tested with a mix of the following SCSI disks:
IBM DDYS-T18350M (18GB U160 SCA) IBM IC35L036UCDY10-0 (36GB U320 SCA)
I'm currently running 2.4.20 with 4 U320 disks and no U160 disk in the how swap cage. The system is now up for about 6 hours and no SCSI timeout occured so far (this doesn't say anything. Sometimes it takes 24 hours before a SCSI timeout or even a freeze occurs) [...]
I haven't got an answer to this report, but with a all-U320 configuration I never had system freezes since. Does the new driver now work in a U160/U320 mixed configuration, too?
