I did, in a previous incarnation of this thread 2-3 days ago, post the
lsmod output and a section of the log showing (I believe) rampant dma
failures. It also didn't generate any comments.

FWIW, I have reinstalled the tarballs version of the drivers, but that
was of no use, so its definitely something in the RT patch itself I
believe. 2.6.12-rc1 works great. By default.

As far as my being able to fix that, I'm afraid I'll have to plead
NDI. The last time I dealt with dma, was on an rca 1802 cpu, which
had its own builtin dma controller that took care of everything but
the pointer reload for the next 6 byte fetch, and which I used for 6
bytes per field of video to feed a homebrewed character generator I
made out of ttl chips, to generate the academy leader on a
commercial. The year was 1978. A bit far back up the log for even
me, altho I may still have a copy of the machine code I wrote that
ran it at KRCR-TV in Redding CA for a decade that I know of, maybe
longer.

That is neither here nor there now of course, just shining a light
back up the calendar about 27 years for illustration.
