[udevd] _very_ high cpu usage.. (solved)

Hi there.
Since I'm under Arch Linux (near 1 year), I always had a problem with udevd and my cpu usage. Before I thought it was a kernel issue, so I did all the updates I can, but no changes..
Sometimes, when I idle, my cpu fan make some noises, so I watch htop, and I see udevd at 99% of my cpu usage... It's very annoying, no ?

I never can solve it, since 1 year.. So I turn to you..

Thanks in advance if anyone can help me

If you couldn't solve it for one year, you clearly had enough time to use the search function:

Bug report

In essence: If you have an optical drive from NEC/Optiarc, do a firmware upgrade.

You were totally right. Sorry
Now, I have 0% of CPU used when I idle

If it can helps someone, I used this file under Windows to update my firmware : http://www.box.net/shared/d0xhgrsuo2

No worries. Thanks for the upload, it might help some people. Could you add what optical drive you have so people know what it's for?

I'm bumping in case I am not the last one to find out that the 2.6.35 kernel solves this problem.
