high load on x4100

hey all,my new x4100s running linux sit at a load average of 8+, even when idle.this page http://www.mail-archive.com/linux-il@cs.huji.ac.il/msg45814.htmlmentions a workaround, by rmmodding ohci_hcd - however that kills usb, which i need.any ideas?

What version of linux are you using?

A load average of 8+ means something is truly wrong. My 4100s running RedHat Enterprise Linux V3, Update 6 have a load average at idle of 0, as they should.

Did you do a 'top' to see what is consuming the CPU?

Here is a list of the modules loaded on a typical 4100 in our shop:

You might want to compare your module list to this one. We have USB support and no high load averages.

this is the OP (the login system the SDN forums use is whacked...)

anyway, i'm running Ubuntu 6.06 LTS (Dapper). i was using their .config on a 2.6.18 kernel plus nfs patches.top showed nothing, except load being way high all the time, while it was known to be idle.

rmmod'ing the module would fix things up, but drop USB, so keyboard and mouse wouldn't work.

anyway i rebuilt a new 2.6.18 kernel and turned off all kinds of modules that didn't look like they were needed.things are happily running at load 0 when idle now.

thanks for the reply!!
