Comment 1 for bug 222174

Bug also exists in 2.6.24-17 Generic. I also must apologize that I labeled the Kernel version's wrong: 2.6.24-16 Generic is the Kernel I was having problems with originally. The kernel that works fine for me is Gusty's Kernel 2.6.22-14 Generic (my extreme bad)

With Kernel 2.6.24-17 & 2.6.2-16 I can manually remove B43 (modprobe -r b43) to eliminate the APIC error (which stabilizes my system). Both the effected kernels will load ndiswrapper driver, but neither kernel's ndriswrapper will load the windows driver despite the windows device driver showing present when ndiswrapper -l is executed. I also toyed with blacklisting the b43 driver, unloading the ssb driver, and even tried to blacklist the ssb driver - no joy in getting ndiswrapper to take over with the Windows driver. Ndiswrapper works 100% with the Windows Broadcom drivers in the old Gusty 2.6.22-14 Kernel, which is why I've reverted to an older kernel for the time being.
