Description rddavis1 1999-08-26 22:31:10 EDT
I have a Sun Sparc5, and after upgrading my kernel from
2.2.5-15 to 2.2.5-22, I get numerous scsi bus resets that
I didn't get before the upgrade.

In /var/log/messages, besides the scsi bus reset messages,
another message I noticed was "AIEEE wide msg received and
not HME".

After looking around in the source code, I saw that the
message originates from /usr/src/linux/drivers/scsi/esp.c
function - check_multibyte_msg().

The scsi bus resets occur in two cases on my machine:

1.  during the boot sequence

    During the boot sequence, just before the login screen
    appears, the disk drive starts clicking (meaning the
    scsi bus resets are occurring).  It clicks for almost
    2 minutes with just the blue blank screen before the
    Redhat login screen appears.

2.  Whenever a command involving files on my second disk
    drive is run.  (i.e. ls, cp, mv, etc.)


From the file /var/log/dmesg...
