hallo !
I have all the time the following problem with my Adaptec 2940UW.
Everytime I have heavy disk-operations (e.g. cron.daily with
rebuilding the locate database => find on whole filesystem)
I get the following ``misbehavior'':
In /var/log/messages appears:
Apr 15 20:25:21 khh kernel: scsi0: Queue full.
approx. 10sec later the scsi devices recieve a reset signal
and the whole Linux is freezed till the Scsireset is
accomplished(15sec more), the full message script (see below)
is updated to my message window and everything seems normal again.
Setup:
2940UW, Bios 1.23 (Boot log see below)
Quantum UW Harddrive
Plextor non-wide CD-Rom (6x) (how do you know it's really Ultra?)
usual Bios setting:
Ultra and Wide enabled for HD,
Initiate Wide negotiation disabled for CD-Rom
automatic termination
synchronous enabled
Kernel: Linux 2.0.29 (had the same problem with 2.0.0)
tried solutions:
disabling Ultra speed
disabling synchronous mode on HD and/or CD-Rom
changing the setting of SCB paging, number of
SCB's (2,4,8,16) (=> If queue full occurs linux hangs with
fast scrolling error messages)
If you need anything else for a diagnosis, please ask.
Has anybody suggestions how I can get rid of this?
Since Windows NT3.51(adaptec driver), NT4.0 (windows driver) and DOS
(adaptec driver)
don't have the same problem, no matter how much I/O load I produce it
seems
unlikely too me that it is a hardware Problem, so I will follow any
Hardware related suggestion too of course.
Thank you very much for any idea,
Karl-Heinz
