Hi@
Here is a bug report for IDE extended twice, with updates.
I forward it here, because I thought I sent it to Andre, but now I think,
maybe I can better reach him here.

Even worse: with your 0111 patch it frrezes hard without a printed error,
just at the beggining fscking the volumes not unmounted clean. Currently I
have hdparm -d0 for all drives at the beginning of sysinit, so I can only
operate w/o dma, so the server function is onoperational.
Can you help w/ advices/some patch?
