RTAI provides its scheduling accuracy in part by trapping
all normal Linux interrupts. I am guessing that the USB system
is producing interrupts that RTAI can not trap. It appears that
there are interrupts generated by the USB system that function
at a level below the usual Linux interrupt handl
Are you using the BIOS USB legacy keyboard emulation?

Hello USB developer list
We are using the RTAI patched kernel for hard-real time
scheduling of tasks. When USB is enabled in BIOS and when
making use of a USB keyboard and mouse we get unacceptable
jitter in the otherwise rock-solid scheduling provided by a
RTAI kernel. I was hoping someone can s
