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

[Redman]

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...

Perhaps worth a sticky ?
