copying my message to everyone else manually because gmail ate my CC. Hi there,
Steps a. and c.: Neither 3.3.0-rc6 (from snapshots), nor 3.2.21, nor 3.2.20 reproduced the bug. I'm typing this email from 3.2.21 right now with a fully functional wireless connection. I skipped step b. due to not having a bad bisect to refer to. Step d.: 3.2.25+ including the attached patches also failed to reproduce the bug. Not sure where to go from here but I'll keep digging if you point me in the right direction. sney On Sun, Aug 5, 2012 at 2:37 AM, Jonathan Nieder <jrnie...@gmail.com> wrote: > tags 681232 + patch moreinfo > quit > > Hi, > > Russ Lind wrote: > > > For what it's worth, the 3.5-1 kernel from experimental works for me > [...] > > I'd also built the 3.4.7 kernel from the sources at kernel.org. > [...] > > I've read about a number of people having this issue thru the 3.3 > > kernels with various distros, and read the issue was supposedly > > fixed in the 3.4 branch.
