I've hit this problem as well on a G5 with Radeon, in Feisty final. Driver package version is 6.6.3-2ubuntu6.
With Ben Herrenschmidt's help, tracked the problem down to an Ubuntu patch which adds some VBE based DDC probing code to the driver as a fallback. That gets triggered on powerpc, and VBE attempts to load int10 which fails horribly, hanging the machine. Attached patch fixes the problem by disabling the vbe code on powerpc, though I don't know that it's really a correct fix. ** Attachment added: "Disable VBE probing on powerpc" http://librarian.launchpad.net/7389400/109_radeon_no_vbe_on_powerpc -- xorg fails with ati driver with feisty on Apple ppc (post herd5 update) https://bugs.launchpad.net/bugs/93509 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
