when dma enabled by default, hangs
No time for exact investigation as the computer is here only for
installation.

There is SMP MB, UP kernel.
SCSI HDD

IDE CDROM: CRD-8400B,ATAPI CD/DVD-ROM drive

hdparm utility says on /dev/hdc:

getmultcount
getnovers
getgeo
all failed

without DMA, it just works,

Elmer.
