    kernel > 2.6.8-1.5 problem: sym0:0:0:phase change message


    After upgrading my server with several ultra 3 scsi drives,
    I installed RHEL4 on it. The installation went without any problems.

    BUT... when the system rebooted, I noticed during post a long list of messages and it kept on reporting the same thing:

    sym0:0:0hase change 6-7 11@1f52b784 resid=6.
    sym0:0:0hase change 6-7 11@1f52b784 resid=6.
    sym0:0:0hase change 6-7 11@1f52b784 resid=6.
    sym0:0:0hase change 6-7 11@1f52b784 resid=6.
    etc....

    An additional problem is the fact that the consoles (tty1, tty2, etc.) are not easy to use since the "sym..." message keeps flooding them...

    After going through the internet, I found more information about the problem: read this bugreport for detailed info.
    It's a bug dating from around september 2004 (read here)

    In other words... this was a frequent problem, and still is!!
    And it seems that there is no solution (yet).

    As far as I found out, kernel 2.6.8-1.521 is the latest "problem-free" kernel to use.....

    People who are running a system using the sym53c8xx controler with SCSI drives, stay away from any kernel newer than kernel 2.6.8-1.521... otherwise you're in for some trouble...
