Subject2.6.21-rc3-rt0 hang randomely + usb can't set config #1, error -62
Hi all,

My system hang randomly with a 2.6.21-rc3-rt0. I also have a
2.6.19.1-rt15 that is working fine. I googled a lot and find at I missed the
shift to the APIC timer with such rt kernels with the 2.6.19-rt15. I try to
enable it in the 2.6.21-rc3-rt0, but it continue to hang from time to time.

/proc/version:
Linux version 2.6.21-rc3-rt0 (root@localhost) (gcc version 4.1.1 (Gentoo
4.1.1-r3)) #1 PREEMPT Fri Mar 23 15:48:12 CET 2007

I get no Oops.
