Re: kernel panic during boot for ata trouble

:Hi,
:
:I've download:
:http://chlamydia.fs.ei.tum.de/pub/DragonFly/snapshots/i386/LATEST-Release-1.6.iso.bz2
:
:and I tried it on a old PC with AMD Athlon 700MHz. and Asus A7V mobo.
:That mainboard has 2 controllers (one Ultra66 and other Ultra100) and 4 ata channels; I've only one hd ata100 master on ata2 channel.

    Hmm.  It is panicing on a wild pointer on line 739 of
    sys/dev/disk/ata/ata-disk.c:

    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 ?

:kernel type 12 trap, code=2
:stopped at ad_interrupt+0x38a: movl %eax,0x148(%edx)
