Tribe 4 - no ICH8 Mobile PATA Controller support for pciid 0x8086 0x2850

Bug #127163 reported by Persio on 2007-07-20
Affects Status Importance Assigned to Milestone
linux-source-2.6.22 (Ubuntu)

Bug Description

Binary package hint: linux-source-2.6.22

I installed Gutsy tribe-2 in this notebook Lenovo 3000 V200 using the Alternate CD. After the installation I noted that the CDROM wasn't working. the fstab file shows that it should be at /dev/hda, but there is no such device. This bug persisted even after upgrade to kernel 2.6.22-8.
After some googling I found out that it is an old problem related to the sata hard disk (which is working).
I also found that I can access the CDROM with "sudo modprobe ide-generic", but then I have no DMA to the drive.

The problem was solved by the team. The problem was the new santa rosa Intel chipset that was not recognised by the ata_pxii module. See:
Now is up to the Ubuntu maintainers to apply the patch to the kernel source.

I am seeing this bug too on a HP Compaq 6710b - waiting for the next kernel package upload to test the fix.

I have a SATA disk in the Ultrabay of my Lenovo ThinkPad T61 and whatever I try it does never show up as
SATA. It is not even discovered as ATA unless I load the ide_generic module
by hand, but then it does not do DMA and is slow.

There's a lengthy description of the problem from Theodore Tso at

Does this fix make it show up as SATA?

When will there be an updated Kernel from Ubuntu available?

I use (K)Ubuntu Gutsy Tribe 4

I have a Zepto Znote 6625WD which uses the same mobile IDE controller and am experiencing the same problem, my dvd drive is not being recognized. Unlike some of the other users above doing a "sudo modprobe ide-generic" doesn't seem to help.

New kernel (2.6.22-10-generic) fixed it for me on a Dell Inspiron 1420. Optical drive is detected and just played a DVD without issue.

The fix in the new 2.6.22-10-generic kernel hasn't worked for me. DVD drive is still not recognized on my Zepto Znote 6625WD.
