Hi there,
This is reproducable with both gcc 2.7.2.3 and gcc 2.95.2. I also had this
problem with 2.2.13 + ide patch.
The box is a K6-2/350 on a Gigabyte GA-5AA motherboard. The chipset is the
ALi Aladdin V AGPset. It has an ST34321A 4.1G HD as hda and an HP CD-Writer+
7200 as hdc. Following the various HOWTOs I am using the IDE-SCSI emulation
to drive the CD-Writer. I left out the IDE-CDROM driver.
If I build a kernel from the pristine 2.2.14 sources, everything is fine
except for not having (U)DMA enabled on the HD. I've succesfully burnt a
CD-R in this configuration, so performance isn't a problem.
If I build a kernel with the ide patch, I can't mount the CD. I get this
error message on the console 80-300+ times before mount spits the dummy:
ide-scsi: The scsi wants to send us more data than expected - discarding data
Now that I look at kern.log, it seems that the problem with remapping DDO
partitions has also recurred.
hdparm has this to say about the HD and CD:
