Hello All,
Perhaps someone, can help me.
I have a multiboot system that boots linux, dos and windows NT.
Linux sits on an ide drive, and i have two Quantum SCSI disks, a narrow
fireball 1 gig and a wide Atlas 4,3 gig on an adaptec 2940UW scsi card.
Now, as far as the hardware side is concerned, this combination flies.
I have no cabling and/or termination problems, and i have yet to loose a
single byte -under NT and dos that is.- 8-((
Linux is a different story.
When Linux boots, and it fires up the SCSI card, the driver gives an endless
array of error messages that all start with: Queu full....and then go into the
particulars. (partly copied further down)
These messages repeat themselves whenever i access the disks, and every time
i go down in a directory tree. This takes about 5 minutes every time.
in order to get a decent running system at all, i found, after lots (and
I mean lots!) of experimentation that i firstly have to disable the wide
negotiation on the card for the wide disk.
Then i have to throttle the narrow disk down to 8 MHz and the Atlas even down
to 6,7 MHZ !!
Only then will linux graciously run, but 30% slower than dos. Unless I change
the motherboard frequency from 66 to 60 MHz, then I can speed the wide disk
up to 8MHz again. AAARGGHH!!!!!
Now, I waited 30 patches long so that this little problem could be resolved
via the regular channels. Unfortunately I am too old and stupid to start
hackin in the code to solve this myself.
Please help me. I will send you all the syslogs that I can find, perform all
the experiments that are needed, and I will mention you in my will.
TIA Joop Bollen
