I'm trying to find out more about this errors.

Today I compiled:
2005-05-27: ok, it seems (I am using it now and want to run it
for a longer period of time, to check its stability)

2005-05-28: USB errors:
usb0: host system error
usb0: host controller halted
Then freezes after exiting X (maybe, because I'm using a USB mouse)

I compiled once again:
2005-05-31: same USB problem
I did a "halt -p" to avoid freeze.

There are not many changes left between May 27th and May 30th, I ran
the kernels only a short time, because of these USB problems. This
time I did not get any DMA errors.
