Hi,

I went into the terrible performance hit when rebooted to U3 kernel. I
had to go back to 2.6.9-27.ELsmp (my previous kernel) and everything
seems to be ok again.

The reboot took a lot of time with U3 kernel. I tryed 'ls' in root's
home directory and it took about 2-5 sec even repeated run :-( The
server run U3 kernel for 24 hour or so when the problem arised.

Seems like odd FS issue or so... Anybody other saw similar problem?

I've several boxes with new kernel (some rather busy), and all seems tobe fine. Could be some device driver problem (you haven't mentionedwhat hardware components you have). You'd be probably best ofcontacting support and/or filing entry on bugzilla.
