Re: RTAI Installation on CentOS6

Hello,

   I am still attempting to install RTAI.  I am now patching a linux kernel
3.18.22 with rtai-5.0-test1.  All the patches are applied and the kernel
builds with no errors, but during the boot there is a long series of USB
connects and disconnects and the boot never completes.

I compiled a plain version of kernel 3.18.22 without RTAI which boots
successfully, so the problem is not something like a bad mouse or cable.

I also applied the patch described in
http://marc.info/?l=linux-usb&m=137714769606183&w=2, which appears to
describe the USB connect/disconnects I'm seeing, but the same errors appear
while booting.

I would appreciate any advice on how to diagnose and resolve this problem.
Thank you.

Best regards,
Thomas Hayward
