T61 is not in the whitelist for hdaps

Thank you for taking the time to report this bug and helping to make Ubuntu better. While I don't think it is absolutely necessary it might be helpful if you could also include the full output of 'sudo dmidecode'. Thanks in advance.

Ive added this to my git tree thanks.

Thanks Chuck!

Just in case I am including the output of dmidecode.

On a side note I think I may have been wrong and per the comment in the code:
"Note that HDAPS_DMI_MATCH_NORMAL("ThinkPad T42") would match
   "ThinkPad T42p", "

So all that probably needs to be done is remove the p from:
HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad T61P"),

And it will match the T61 and T61P

I mistakenly put the wrong dmi string for all T61's, some use LENOVO, some Thinkpad.

Chuck I think I made a mistake, the module still doesn't load on my system and when I look at my dmidecode I think the vendor is Lenovo and not IBM anymore. Also the axis readings need to be inversed so it should be:
HDAPS_DMI_MATCH_INVERT("LENOVO", "ThinkPad T61"),

Though what is odd is that my work T61 says IBM in the dmidecode... Maybe different manufacturing locations or Bios revisions?

Is it possible to update hdaps.c before release?

Thanks!

See https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/45014 for a working solution.

HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad T61"),

actually the right one should be:

HDAPS_DMI_MATCH_NORMAL("Lenovo", "ThinkPad T61"),

however it still doesn't work on my thinkpad T61

that's the dmesg output:
[ 19.660000] hdaps: inverting axis readings.
[ 19.660000] hdaps: LENOVO ThinkPad T61 detected.
[ 19.660000] input: hdaps as /class/input/input4
[ 19.660000] hdaps: driver successfully loaded.

but that's the "/etc/init.d/hdaps start" output
* Not starting hdapsd: /sys/block/sda/queue/protect does not exist

I actually didn't recompile the whole kernel but just the modified module hdaps.c

Has anybody tested this on the development release of Ubuntu - Hardy Heron? You can learn more about the development release at http://www.ubuntu.com/testing. Thanks in advance.

I'm downloading the alpha4 release to test hdaps, thanks for the information

See: https://bugs.launchpad.net/bugs/139881

Basically, hdapsd requires a kernel patch, and Ubuntu is unwilling to support it.

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 can confirm that hdaps loads with kernel 2.6.27-7 (Intrepid Ibex 8.10 beta)

from dmesg:
hdaps: inverting axis readings.
hdaps: LENOVO ThinkPad T61p detected.
Input: hdaps as /devices/platform/hdaps/input/input13
hdaps: driver successfully loaded.

Thanks for the note. Marking this "Fix Released" for Intrepid. Against 2.6.22 this will be closed. Thanks.
