ppc32 weirdness with gcc-4.0 in 2.6.11-rc4

2005-02-23 Thread Mikael Pettersson
2.6.11-rc4 built with gcc-3.4.3 works fine on my eMac. Building with gcc-4.0.0 (20050220) however gives me a kernel with dead USB, and thus no keyboard or mouse, but everything else seems to be working. A diff between dmesg on the two kernels has an interesting nugget: --- dmesg-2.6.11-rc4-gcc343
