I will emphasize some more: I want to have all of that drm initialization to happen, EXCEPT do not want to allow it to make display mode change during the boot! Call me a dinosaur, or whatever, but getting the system to boot to text console used to be "guaranteed thing", except that now it is not :-( I do not want windows, I want Linux. When I then see that system did boot correctly, I will MANUALLY start X. I might even permit the init-script to start the xdm or other graphical login manager, but only after the bootup has been completed all the way to userspace! I tried vga=ask on boot line, but of course it did not have effect on drm. > Best regards, Matti Aarnio > > From failing case: > > kernel: Linux version 2.6.31.1-48.fc12.x86_64 > (mockbu...@x86-6.fedora.phx.redhat.com) (gcc version 4.4.1 20090923 (Red Hat > 4.4.1-16) (GCC) ) #1 SMP Fri Sep 25 16:57:40 EDT 2009 > .... > kernel: [drm] Initialized drm 1.1.0 20060810 > kernel: [drm] radeon defaulting to kernel modesetting. > rsyslogd: [origin software="rsyslogd" swVersion="4.4.1" x-pid="1396" > x-info="http://www.rsyslog.com";] (re)start > kernel: [drm] radeon kernel modesetting enabled. > kernel: ACPI: PCI Interrupt Link [APC3] enabled at IRQ 18 > kernel: radeon 0000:01:00.0: PCI INT A -> Link[APC3] -> GSI 18 (level, low) > -> IRQ 18 > kernel: [drm] radeon: Initializing kernel modesetting. > kernel: [drm] register mmio base: 0xC1000000 > kernel: [drm] register mmio size: 65536 > kernel: ATOM BIOS: 11X > kernel: [drm] Clocks initialized !
