Sorry if this is an old issue, but I'm still seeing this problem between
ALI15x3 and Maxtor drives when DMA is enabled...
If I run 2.4.19 DMA is not autodetected. I get lousy performance. I can enable DMA (with hdparm) on all but my Maxtor drive, but if I manually enable DMA on the Maxtor drive disk access freezes (to both drives on the channel).
If I run 2.4.19-ac4 DMA is turned on automatically and the system hangs at the partition check.
on 2.4.19 I see this in dmesg:
...

2.4.19-ac4 (correctly) probes hda and hdb as being UDMA(100), but it looks like hdb chokes on the DMA...

Perfect you have revision C4, you answered the outstanding mystery about
whether C4 is capable of LBA48 or its >C4 that is

i have a liveEVAL cd (SuSE 7.3) and a maxtor hard disk et 686, it freezes on writing bootloader, hangs with a constantbeep.. I wonder if this is related...

Have you disabled you BIOS' bootsector virus protection?
This often causes such beeps...

first thing i did...
