The 'typical' messages from my working 2.1.65 kernel are:
--------------
hda: IBM-DLGA-23080, ATA DISK drive
hdc: CD-316E, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: IBM-DLGA-23080, 2937MB w/96kB Cache, LBA, CHS=746/128/63
Floppy drive(s): fd0 is 1.44M
FDC 0 is a National Semiconductor PC87306
Partition check:
hda: hda1 hda2 < hda5 hda6 hda7 > hda3 hda4
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 28k freed
-------------
The 'unable to get irq 255' message is very suspicious -- I suspect that
something is putting -1 into a byte somewhere, but I was not able to
track this down in the diffs between 2.1.65 and 2.1.70. The CMD646
messages are new, too -- possibly something is going wrong there?
The diffs between my 2.1.65 configuration and the 2.1.70 configuration are
included below my .sig. Full config details are available on request.
Hopefully this helps someone track down a bug. I suspect that disabling
IDE DMA will allow me to use 2.1.70, but for the time being I remain in
2.1.65.
