Error Message Log
john, this looks like b43 is corrupting memory to me. a use after free perhaps?
Michael, for reference this kernel corresponds to the top of the
current "pending" branch in wireless-testing, as well as all the current fixes
sent to 2.6.25. Have you seen anything similar reported?
Gerald, what was the last working kernel for you?
Didn't see that before, but to me it looks more like a mac80211 bug or memory
I backed out to:
and it is working fine with no error message or lockup so far. I also didn't
have the problem with any of the other F9 Alpha kernels.
I receive the error message with the git4 kernel about 1 or two minutes after
boot. Lockup then varies depending on what I am doing. I have to poweroff to
Gerald, please try kernel-2.6.25-0.90.rc3.git5.fc9. It has a patch that cured
a similar problem in yesterday's F8 kernels.
Does that resolve things for you?
kernel-2.6.25-0.90.rc3.git5.fc9 appears to have resolved the problem. The only
thing I noticed was I needed to re-enter my WPA key after the first boot. After
that, the settings were saved. Thank you.
