Instaling Ubuntu Linux on the HP Pavilion tx25135cl

The HP Pavilion tx25135cl is a 12.1″ laptop tablet. It comes with an AMD Turion X2 RM-70 processor clocked at 2.0Ghz per core. Along with an ATi Radeon 3200 HD, this makes it a part of the AMD Puma platform. It has 3GB of RAM, a 250GB hard drive, and is usually pre-installed with Windows Vista Home Premium.

All installation work was done on the Ubuntu alternative installer.

Things that need fixing:
Installation:
You will need to pass nolapic and acpi=off as kernel options, both for installation and normal boot. Not doing this results in a thermal warning (and subsequently a forced shutdown). Specifying other combinations is prone to causing a kernel panic (and subsequently a hard system lockup as a result).

Ethernet:
Realtek Ethernet is severely broken with the RTL8111/816B that gets loaded as stock.
A bug report for this is here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/141343

The fastest way to fix this is to use Jameson William’s fixup. You will want to load the file there onto a USB stick. From a fresh Hardy install (alternative installer), the patch program was not installed, so you may need to grab a deb as well.

Grab the fixup here (read the instructions for it and install): http://www.jamesonwilliams.com/hardy-r8168.html
If you end up needing the patch utility, you can find it here: http://us.archive.ubuntu.com/ubuntu/pool/main/p/patch/
Select the appropriate architecture, download it onto your USB stick, and as root on the affected computer, issue a `dpkg -i patch_[version here]_[architecture here].deb` to install it.

Wireless:
Broadcom BCM4328 a/b/g/n

This Broadcom chipset is VERY nice, it does 802.11 a/b/g/n. However it doesn’t get recognized as stock, and thus it falls over on itself:

This did not work for me on the cl, even though others with similar configurations had working wireless configurations. This may change in the future.

At this point, I decided to return the laptop due to time constraints (I was not able to get to work on the video or tablet features). Hopefully this post helps somebody out.
