Thanks, I'll give it a try ...

BTW,
This time it didn't take several hours, but merely a couple of minutes;
what I did was starting several downloads (onto a ext3 on /dev/hda1),
and then opening up a couple of websites in konqueror (which in turn uses
the proxy that also access /dev/hda1)


Again pdflush was consuming 100%, but this time I waited about 5mins and
pdflush behaved normal again ... just to start again later and disappear
again ...

I still have see the following messages on the serial console:

hda: lost interrupt
hda: dma_timer_expiry: dma status == 0x64
hda: DMA interrupt recovery

and also the same symptoms as before (network is working normal, USB
keyboard/mouse don't work). If you respond fast what commands I should
run, I can give you more info ...


Thanks,
