next in thread | raw e-mail | index | archive | help
I am receiving timeout errors on boot preventing the OS to load when
using an old CDROM drive and a Quantum Atlas IV drive:
SCSI: aborting command due to timeout: pid 0, scsi0, channel 0, id 4,
lun 0, Test Unit Ready 00 00 00 00 00
SCSI host 0 abort (pid 0) timed out - resetting
SCSI bus is being reset for host 0 channel 0
(last 2 lines repeat indefinitely)
With the same hardware configuration, I did not receive these errors
with the Linux 2.2.3 kernel, but they I first came across them with the
2.2.10 kernel. Also using the Adaptec SCSI software under DOS does not
result in any obvious errors (no errors are displayed during loading).
I have looked through the archives and looked at termination issues as
well as trying the "no_reset", "panic_on_abort", and "override_term"
parameters at bootup. Following is my configuration. If I provide
anything else that would be usefull, please let me know. Thanks in
advance.
System Configuration:
Redhat Linux 6.1 with 2.3.49 kernel (aic7xxx support is compiled into
the kernel)
AIR 54TPI motherboard with on board AIC-7880P SCSI chip
68 pin connector
Quantum Atlas IV 9GB harddrive
End of ribbon cable is terminated
50 pin connector
Chinon CDS-535 Internal CDROM Drive (SCSI-2 drive)
End of ribbon cable is terminated
(Have also tried using middle connector on ribbon attached to
motherboard connector and terminating both ends)
No IDE devices
