I have run the same Hardware unter 2.2-stable for about 8 Month without
problems. After updateing to 3.0-Release the problem started with
one or to retries. I Have cvs uped some times to Current. With changeing
results. I have uses a kernel build with a system an cvsupd un teh 6.

the second Try). I cvsupd tu 3.0-stable hoping the problem might be fix
there. But its still There
