Most recent kernel where this bug did *NOT* occur: 2.6.18-r3 Distribution: Gentoo Hardware Environment: iBook G4 Software Environment: Any Problem Description: After I upgraded to this kernel version my airport broke entierely inside Mac OSX. Resulting in a kernel panics on OSX, OpenFirmware illegal instructions, etc.. It could be completely coincidental, but better safe than sorry. Steps to reproduce: Upgrade to 2.6.19-gentoo-r1, boot back to OSX, get iBook to sleep. *death*. In order to get it to boot again I resetted te logicboard by Fn-Power, I could boot back in Linux and safe my data. The MacOSX crash is easy reproduced. If the airport is on, the system will crash. If you turn the airport on the system crashes. Again, I'm not entirely sure if the kernel upgrade caused this. But before I'm going to send my iBook for repair I want to make sure this isn't some (bug) in Linux, doing something nasty with the hardware.
