Huh. How can I do so without being a subscriber of the kernel

Looks promising:

./2.6.12-EHCItest/linux-2.6.12-rc1/drivers/usb/host/ehci-sched.c.rej
./2.6.12-EHCItest/linux-2.6.12-rc1/drivers/usb/host/ehci.h.rej

vi /usr/src/linux/Makefile

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 12
EXTRAVERSION =-rc1-ce

uname -r
2.6.12-rc1-ce

Seems I've been successful compiling and installing the 
kernel. Thanks for the help!

Yes, seems to be running, and there are surely xruns!

Well, the xruns are bad, but I'm happy to have the patched 
kernel running, regardless that the bugs are still 
there ;-) .


 Thanks a lot & best regards
