Comment 8 for bug 137538

Hi,

got the same problem. I reported #149033. As I reported, there, I could work around this bug by blacklisting the battery kernel module, so it definiately must have something to do with the changes made there. The one time I was able to completely log in, the difference I saw was the following: Previously (feisty and predecessors) because of the laptops broken DSDT the battery was just reported as not present. What I saw when I logged in was that it reported no power cable present but instead an empty battery. Unfortunately I don't know enough about fixing DSDTs. I tried to fix mine (using common sense) but only got kernel panics.
Please tell me. if you want me to assemble the above mentioned information, too. I could also post the DSDT if that helps.

One other thing: all the ACPI stuff worked perfectly under breezy on that laptop.
