Re: kernel panic during boot for ata trouble
nice to meet you again (since Amiga DICE time). I appreciate your DFBSD project.

Hmm. It is panicing on a wild pointer on line 739 of
request->bio->bio_buf->b_resid = request->bytecount;
Either 'request', 'bio', or 'bio_buf' is a wild pointer.
Could you do a 'trace' from the DDB prompt ?

I fear that such problem was generated by SATA and parallel ATA cables in the same box, then I've disconnected any SATA cable but this error appears in same way.
DragonFlyBSD doesn't detect yet the Promise SATA 300 TX2plus (PDC20775) pci board and devices connected to it.
Can I do something to have support for that controller?
Thank you in advance, \fer
