Apple Mac G5 and T2/Linux
The latest, greated and last PowerPC based systems from Apple Inc. The machines featured up to two dual-core IBM 970 64-bit CPUs.
Notes and quirks
Suspend to RAM does not yet work, patches for suspend to disk are available.
Switching back and forth to the text console and back to X causes system lockup every 2nd time. As noone else appears to experience this problem we are under the impression that it is related to the 64bit X server and driver (other distribuions only ship a 32-bit user-land) - probably due to alignment or padding issues some chip state is not restored properly. Update: Apprently some update resolved this recently (maybe the libpciaccess migration?):
