  As you might imagine, hdparm was the first thing I tried. It seems not
  all of hdparm's features work with libata-based drivers, in particular I
  can't disable/enable DMA with it:
  
  r...@cartman:2005:/home/russudo hdparm -d 0 /dev/sda
  
  /dev/sda:
   setting using_dma to 0 (off)
   HDIO_SET_DMA failed: Inappropriate ioctl for device
   HDIO_GET_DMA failed: Inappropriate ioctl for device
  r...@cartman:2006:/home/russudo hdparm -d 0 /dev/hda
  /dev/hda: No such file or directory
  r...@cartman:2007:/home/rus
 
  Sorry, I thought most hdparm features would still work.
 
  You can still disable DMA by setting a module option for libata.  Put
 
 Or by using a kernel command-line option (e.g. libata.dma=0 which I'm
 using for now). But with hdparm I could turn it on and off at run-time,
 which is useful on one particular machine I use, and which I don't
 believe is possible now.
 
 I think if changes to the kernel package are partly breaking another
 package, which I've demonstrated is happening here, that seems like it
 should count as a bug in Debian. Maybe hdparm or even sdparm is more to
 blame, I don't know, but I think this has to be a regression somewhere
 doesn't it?

OK, sure, it's a regression.  It is unlikely to be fixed, though, as
there is very little reason to control this at run-time.

Ben.

Bug#587418: linux-image-2.6.32-5-686: using old IDE driver fails, probably due to missing ide_pci_generic module

2010-06-28 Thread Russell Marks 
Package: linux-2.6
Version: 2.6.32-15
Severity: important

The 2.6.32-5-686 kernel uses libata rather than the old IDE driver,
which is fine I suppose, but I wanted to use the old IDE driver so I
could still use hdparm for e.g. enabling/disabling DMA post-boot (I
could go into why, but you probably don't want to know :-)). I
eventually figured out how to do this, but it kept waiting for the root
all the time. A bit of poking around later, I realised
ide-pci-generic.ko was missing from the initrd, so I checked my real
/lib/modules and sure enough, it was missing from the 2.6.32-5-686 tree.

I could be wrong, but I think this means the old IDE driver is largely
impossible to use without building a custom kernel. Since *most*
old-IDE-driver-related kernel modules are still being built, I presume
this was unintentional, so I'm reporting it as a bug.

I can only guess at how general this problem is, so I'm reporting it for
the particular package I've personally had the trouble with.
