toshiba laptop satellite m40 acpi issues

Hi,

I have a Toshiba laptop too (Satellite pro A200) and I have the same problems with ACPI under 9.10, but not under 9.04.

I have been reading some documents over the Internet, and it seems that the problem lies in the lack of compatibility between Toshiba BIOS (Phoenix series especially) and Linux.

I am not an expert, but this claim seem credible, given the ACPI problems that we have. I am not aware of any recent BIOS updates from Toshiba (in my case, the last one was in February), so I believe we can only hope that Ubuntu developers can focus on this problem in the future releases of the distro.

Good luck.

I also have seen no updates, my last bios was last updated several years ago by Toshiba. I have seen some works around by people with much deeper programming knowledge than I have. I suppose the real problem is that I am unsure of my abilities and so unsure of implementing similiar solutions as they have found but not under supervision. The solutions I saw involved changing the bios code itself. still it might keep me from having to replace my machine before its time.

try issuing the following command:

sudo ifconfig wlan0 down

if your wireless card is not wlan0 substitute the right identifier for wireless.

Charles,

Would that command be sufficient to solve the ACPI issue?

In my case, Karmic (9.10) was notifying an acpi problem related to the battery state retrieval, which is linkable to my BIOS, evidently not entirely compatible with Ubuntu.

Rogerb,

I read of some workarounds related to the old series of Toshiba BIOS, maybe you can still try that. But they also said that for the newer BIOS series (Phoenix) there is nothing to do. Let's pray that Ubuntu developers can come up with a good solution.

Besides, the beta version of Karmic has switched to a new power management, therefore I believe the code is not perfected yet:

"Ubuntu 9.10 Beta's underlying technology for power management, laptop hotkeys, and handling of storage devices and cameras maps has moved from "hal" (which is in the process of being deprecated) to "DeviceKit-power", "DeviceKit-disks" and "udev". When testing Ubuntu 9.10 Beta, please be alert for regressions in those areas and report any bugs you find. " (Source: http://www.ubuntu.com/testing/karmic/beta)

Sigh, this is only the second time I have been advised to pray...lol...never
a bad idea i suppose.Still, at this point I am beginning to think that a new
machine might be the answer...something without a Phoenix or Toshiba Bios.

Thanks for your kindness in responding to my plea.

My command just deals with an issue that failed to properly shutdown wireless cards that hung shutdown... the displayed message dealt with ACPI, but the message was just where it hung... not the actual issue.
