Please at least tell me to go away ;^) I was poking around in arch/ppc/kernel/head.S and I noticed this: oris r18,r8,0x20000000@h oris r21,r11,(KERNELBASE+0x20000000)@h mtspr DBAT2L,r18 /* N.B. 6xx (not 601) have valid */ mtspr DBAT2U,r21 /* bit in upper BAT register */ mtspr IBAT2L,r28 ^^^^^^^^^^^^^^^^Wouldn't r18 make more sense here? mtspr IBAT2U,r21 Has anyone tried to build/run a pmac SMP kernel with a recent (2.2.9) version of Linux? o I've got a 9500 with 2 604e/200MHz. o A UP kernel works fine. o Compliling the same kernel with the SMP support box checked results in a kernel that doesn't boot on UP(a G3) or SMP(the 9500) machines. o I also replaced the dual card with a single 133 MHz CPU, which also fails to boot the SMP kernel. Can I expect a SMP kernel to boot on a UP? I thought so, although it might be slower than a UP kernel on a UP. The symptoms are that it gets to the point of "opening the display", which activates the display (all white, I assume painted that way by OF), prints "copying OF device tree...done" and stops.
