Jeff,

Can you reproduce with 2.6.18.1?  ES4 contains a custom 3ware driver.

We don't use kernels later than 2.6.15 in our shipping releases since they have some issues with stability.

Also, you have included no error output with this email whatsoever.  Can
you go to a virtual console during your ES4 install, run 'dmesg', and see if the errors are in there, or if they are a part of the ES4 anaconda installer?

dmesg produces no output since the errors are reflected from init.

Errors are typical of an unmounted volume. i.e.
"cannot touch /var/lock/subsys/<service> (dozens of these)
Starting System logger (hangs for 15 minutes)
So no logs .....


/dev/sdb, etc. having delayed appearances sounds like it is udev related.

No, I do not believe so.


Are you running the latest firmware? Do your controllers older than 60 days
have different firmware?

This is the right question. I will collect the various versions this occurs on and post them here.


I will try to reproduce this.

Pretty easy to do.
