From: Oz Nahum Tiram <nahu...@gmail.com> To: Ben Hutchings <b...@decadent.org.uk> Subject: Re: Bug#601345: linux-image-2.6.32: wrong battery charge level Date: Mon, 25 Oct 2010 19:08:59 +0200 I have compiled linux kernel 2.6.34, and I have installed all the linux-kernels with vesions 2.6.31. At the moment, I have 3 operating systems on this laptop. Debian Squeeze Ubuntu 10.10 Ubuntu 9.10 When I install the kernel package of Ubuntu 9.10 (2.6.31) in Ubuntu 10.10, this issue does not occur. I could not find a debian package of 2.6.31, but like I said, I tried all the others possible, and it did occur ... So I believe that this issue is kernel related.
