Public bug reported:
I have been running Gentoo on an Asus Pundit-R with an SATA hard drive.
The SATA support on this barebones' motherboard is from an onboard IDE
to SATA converter, with the result that the SATA drive appears as
/dev/hdc on the IDE bus.
The problem seems to be caused by the incorrect detection of a 40 pin
ATA cable, thus limiting the transfer speed to Ultra ATA 33. The
following patch allows detection of when an SATA converter is being
used, and is incorporated into the 2.6.18 source tree, but is not
present in either the Edgy or Dapper kernel.
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=1a1276e7b6cba549553285f74e87f702bfff6fac
Since kernel version 2.6.14, I have been using my own patch (which does
essentially the same thing), but I would like to switch to Ubuntu on
this machine and do not want to have to manually patch the kernel, each
time an update is released :)
I'm sure this can be committed to the Edgy kernel, and if it could be
applied to the Dapper kernel I would really appreciate it - the
structure of this part of the ide-iops.c file has not changed for many
kernel versions.
Thanks for your help,
Michael-Luke Jones
