Subjectproblem solved - late answer.. (was: Re: DMA problems w/ PIIX3 IDE, 2.4.20-pre4-ac2)
Hello!

Quite some months ago I raised some questions, got some answers and
continued working silently until my problem was solved. While digging
the archives for yet another IDE problem today I realized I did
not send any message to you guys nor to the list afterwards.

Just in case someone is interested or cares still:

1) Sorry for not sending a "problem solved" mail when it was solved
2) My box is running smoothly again. It was neither a kernel issue
nor a hardware problem with the disks. Different kernel versions
did behave differently, but the cause of it all seems to be a broken
CPU (or broken jumper settings).
Installing a new CPU made all problems go away. And the box is
rock solid with or without IDE-DMA turned on.


Regards
Florian


P.S: A little block quoted below in case someone wants to remember what
this was about:
