Please read: sym0:0:0:phase change message problem!

[Patrick]

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:

sym0:0:0:phase change 6-7 11 at 1f52b784 resid=6.
sym0:0:0:phase change 6-7 11 at 1f52b784 resid=6.
sym0:0:0:phase change 6-7 11 at 1f52b784 resid=6.
sym0:0:0:phase change 6-7 11 at 1f52b784 resid=6.
etc....

What also was a problem, was that the consoles (tty1, tty2, etc.) could not be easily used since the "sym..." message kept flooding them...

After going through the internet, I found more information about the problem:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=139949

It's a bug dating from around september 2004:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=139949#c10 

In other words... this was a frequent problem, and for some odd reason still is!! It seems that there is no solution (yet). And as far as I found out from the bugreport, 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,   can't use FC3, FC4t1 or RHEL4 (kernel 2.6.9-5.EL). Also CentOS4.0 has the same problem, but that's a different story ;-)

So, just to bring this to your attention, please have a look at it. Perhaps it's something worth fixing for the future??

Regards,
