Hi,
I've just bought a second hand Seagate SCSI disk to use with my SPARC
IPC. I've been installing RedHat 5.1. The install works fine, but
rebooting off the installed OS generates the following:
esp0: IRQ 3 SCSI ID 7 Clock 25 MHz CCF=5 Time-Out 167 NCR53C90(esp100)
detected
ESP: Total of 1 ESP hosts found, 1 actually in use.
QPTI: Total of 0 PTI Qlogic/ISP hosts found, 0 actually in use.
scsi0 : Sparc ESP100 (NCR53C90)
scsi : 1 host.

Trying to mount the CDROM after login generates more of the same.
Eventually the CDROM mounts OK and I can use it. Trying to use a second
hard disk in the system causes it to lock up completely during boot. Can
anyone suggest a possible cause for the error messages? Or what the
installed kernel is doing that the boot disk image doesn't? If it is
doing something different how can I stop it? (I've already tried
patching the SCSI code to stop it scanning unused luns. Either I did it
wrong or it makes no difference) Is it significant that the number of
sectors in the last message is more than
the disk data sheet says exists on the disk?
Answers to any of the above would be appreciated. I've been trying to
get this going for three weeks. with about six different disk labels. I
can't find anything which will eliminate these messages. I have to admit
I'm totally out of my depth :-(
