Hi Marc-Christian,

i applied the patch over 2.4.21-pre5 and did some more testing.
I'm still having a problem but a different one ( i strongly suspect it's
due to the patch since i never had this before and this occured when i
tried to reproduce my previous problem ).
Here's a exerpt of the logs:

Mar 12 10:19:38 localhost kernel: hda: dma_timer_expiry: dma status ==

and basically the whole machine locked up ... reset was the only way out :-(
I have an ASUS A7V8X motherboard with a VIA Technologies, Inc. VT82C586B
PIPC Bus Master IDE (rev 06)and a Maxtor 6Y080L0 hard drive.
Any other idea/hint to solve this ?
Thanks again for your help
