PBG4 12" sometimes disk problems during boot

[Pander <pander@users.sourceforge.net>]

Hi all,

Since a few days my PBG4 12" will not always boot completely. Somewhere 
at the end of the boot sequence, just after it is loading some sound 
stuff it says (something like):

.
hda: lost interupt,
hda: lost interupt, lost dma status: 8080

And then it hangs... Then I try again and all goes fine. Does this mean 
my harddisk is not stable anymore or that is had problems when it is 
cold, because we all know the current normal operating temperature for a 
PBG4 now. Or is it a result of too many (unneed) ext3 disk activity when 
Linux is running and this is wearing out my harddisk?

I'm starting to get very worried about my machine now, anyone has some 
pointers to fix this or can give me a clue about what is going on?

Thanks,

Pander
