Bug Description

Hi,

after upgrading from feisty to gutsy, the system performance is slow.
Apparently DMA access to the hard disk is disabled:

$ sudo hdparm /dev/hda
/dev/hda:
multcount = 0 (off)
IO_support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 78126048, start = 0

enabeling fails:

bassler@grgawlan:~$ sudo hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

inserting "piix" in "/etc/modules.conf" did not solve the problem.
$cat /etc/modules

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

piix
lp
mousedev
psmouse
fuse

dmesg claims:

Values reported in previous post are for 3.5" 160GB 7200rpm IDE HDD running under Ubuntu Hardy on an older desktop motherboard. [Other operating systems installed on the same machine seem to have much better HDD perforamance.]

2.5" 60GB 4200rpm SATA HDD on notebook under Ubuntu Hardy:

dev/sda1:
Timing cached reads: 1364 MB in 2.00 seconds = 682.38 MB/sec
Timing buffered disk reads: 84 MB in 3.06 seconds = 27.42 MB/sec

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I'd like to try the new kernel on my Hardy install.
Can I find a binary package somewhere to install, or do I have to compile from kernel source?
(I spent 20 minutes googling and have not found a binary install as yet..)
