ok, the nice1 defaulted to zero did not fix it but enabling the VIA
support yes, arghhh !!! i was using the VIA chipset w/out enabling it in
.config and this made the kernel to not probe it correctly and to force
off using_dma ( and io32bit ). this resulted, besides the ide_set_handler/timer
problem, in an throughput of 3.9 MB/sec against the 24 MB/sec that i'm getting now.
i need a vacation ...


(a couple of weeks ago i screwed up my patch-bot scripts that was hunging
by trying to merge 2.5.6-pre3 on 2.5.6 - not only i considered the
operation perfectly legal but i ended up asking Linus why he screwed up
the patch :-( )
