The Story So Far:
For some time now I have been running RedHat 5.2 (last Kernel was 2.2.9)
with two SCSI controllers:
SYM8750SP (53c875; DDS-Drive and CDROM only)and DPT 3334UW (eata; 5 HDD
as RAID) without any problems.
And Now the Problems:
Reinstallation from scratch of RH6.1: not even the installation worked!
Whilst reading the RPM packages I got a stream of SCSI resets or
CDROM-I/O errors, ending with the machine hanging. The problems where
reproducible.
After connecting the CD-Drive to the DPT controller the installation
went OK.
During operation, however, the errors continued on the NCR controller.
Never ending SCSI-resets.
Changing the driver from NCR to Symbios made no difference.
I think I've changed everything there is to change:
3 different CD drives from two manufacturers (Toshiba and Pioneer)
A different cable
A different NCR controller (SYM8251S with a 53c825)
Running the NCR without DDS drive, just the CDROM
A different PCI slot
Nothing changed. Always the same. Installation impossible. SCSI-resets.
I suspect the [ncr|sym]53c8xx driver causes the problems.
To verify this I installed a RH6.0 derivative yesterday (Halloween III
with 2.2.9 and a few german adaptions). This installation went well and
I couldn't see any problems afterwards.
I have no clue what to do next.
Any suggestions?
