Shortly after all this started, I built linux- source_2.6.28.11.15_all.deb on PPC to see if that later version (the source for then current ia32 version) had the fault, and it did on PPC. Yesterday, following spydouglas' example, I built kernel.org 2.6.28.10, which, as we now know, works on PPC.
This morning, inspecting the differences in drivers/gpu/drm/radeon/radeon_cp.c, I naively changed the three instances of drm_core_ioremap_wc() in the above Ubuntu source (drivers/gpu/drm/radeon/radeon_cp.c) to remove the _wc, i.e. back to the Korg non write combining version (this is at lines 1183-1185), [ ==> drm_core_ioremap()]. The kernel from modified Ubuntu source works with DRM, though I have no idea what the side affects might be. -jh -- linux-image-2.6.28-5-powerpc has ioremap fault with radeon drm module https://bugs.launchpad.net/bugs/345542 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
