New kernel broke for x86_64 (Intel)

["casimiro barreto" <casimiro barreto gmail com>]

I've had a constant problem of getting a Dell server (dual Intel
Pentium 4 Dual Core) locking. Apparently it is an issue related to the
kernel 2.6.19-1.2911.6.4 and the newer ones. It is not handling
correctly USB IRQs and I have a frozen box.

Have someone else experienced the same problem?
