in the logfile you can see the output of 2.6.20-git11, and later,
the newer kernels I compiled, that actually misconfigure the
primary master Seagate HDD at UDMA33
Comment 6 Plamen Petrov 2007-03-30 07:21:55 UTC
the bug was still present in linux-2.6.21-rc5,
just downloaded patch-2.6.21-rc5-git6 and will test
it as soon as possible...
Comment 7 Plamen Petrov 2007-04-04 08:03:24 UTC
linux-2.6.21-rc5-git6 solved the issue for me...
