Dear IDE maintainers,
I recently installed Debian unstable on an old digital personal
workstation 433au alpha (Miata) [1] with the default kernel 2.6.32
from Debian unstable. There were no obvious problems except for the
tulip network driver which produced a lot of noise [2]. Joe Perches was
so kind to provide a patch to reduce the noise. I applied the patch
against 2.6.34-rc3 and rebuilt the kernel with the 2.6.32 Debian
config using "make oldconfig". The kernel build took around 18 hours ;).
Anyway, after rebooting the machine into the new kernel (2.6.34-rc3), the
IDE driver obviously triggered a lot of errors [3] resulting in the kernel
not being able to mount the root partition.
The error message is always the same:
hda: possibly failed opcode: 0x25
drive not ready for command
status error: status=0x5a { DriveReady SeekComplete DataRequest Index }
But please see the screenshots in [3].
The system finally dropped into a busybox. I issued a "reboot" and tried
to reboot into the Debian stock 2.6.32 kernel. However, after the IDE problem
with 2.6.34-rc3, aboot was unable to read the bootsector. When I powercycled
the machine, I could reboot properly into 2.6.32 without any problems. I
already checked the IDE cabling, the harddisk is new, btw. The problem
reproduces every time I boot into 2.6.34-rc3.
It looks like that some changes in the IDE driver between 2.6.32 and
2.6.34-rc3 somehow messed up the code on Alpha. I didn't test the
whole thing on 2.6.33.2 yet, however the machine is busy right now
building that kernel so I can try tomorrow.
The lspci output of the hardware looks like this:
