Description John Reiser 2009-08-27 03:05:16 UTC
+++ This bug was initially created as a clone of Bug #494390 +++
During an initial install from DVD the machine fails to make the transition to graphical mode.

Component versions:

Reproducible: every time

How to reproduce: boot Fedora-12-Alpha-i386-DVD.iso from a real DVD on Apple Mac mini i686-only with Intel 945/950 graphics.

I have verified that the problem originally reported in bug #494390 against Fedora 11 beta persists using Fedora-12-Alpha-i386-DVD.iso burned to a DVD.  Booting and selecting the first choice "Install or update..." gets a hard crash at the transition from text to graphics mode.  The screen goes black, the backlight on the display is off, and there is no response to the keyboard <Ctrl><Alt>F2 trying to get a shell on VT2.  The only option is power cycle: turn off, turn on.

Again using the Fedora 12 Alpha DVD for i386, but selecting the second choice to install with basic video driver, gets a soft hang.  The screen is blank, the backlight is on, I can get a shell on VT2.
"ps ax" suggests that "modprobe fcoe" is going nowhere in async_D+ state.  (There is no Fibre Channel over ethernet on this box.  There is an external harddrive connected via ieee1394 (400MHz FireWire.)

According to Apple "About this Mac" the hardware is:

Examining the Packages directory on Fedora-12-Alpha-i386-DVD, I see:

Since you're trying to boot with 'basic graphics' (i.e. vesa) the bug clearly isn't in xorg-x11-drv-intel :)

CCing Andy in case this has implications for Anaconda also.

Can you capture the output of alt-sysrq-t?

> Can you capture the output of alt-sysrq-t?

Perhaps.  This is an Apple Macintosh Mini, so there is no serial port for kernel serial console.  There also is no netconsole until anaconda builds that module into the install (bug # 519756.)  The keyboard has no SysRq key, but I have a USB keyboard for PC.  So I will try that next morning (PDT), and send a .jpeg photograph of the screen.

Comment 7 John Reiser 2009-09-01 13:04:11 UTC
alt-sysrq-t displays only the single line "SysRq : Show State\n" and nothing else.  Consecutive alt-sysrq-t just repeats that one line.  This is with an additional PC-103 keyboard (having SysRq key) in addtion to the Apple keyboard-plus-mouse.  There is an external ieee1394a harddrive (FireWire 400MHz.)

The soft hang "async_ D+" now appears on "modprobe raid0".  Hmmm, the external harddrive (and/or the ieee1394 interface) seems to be common to the radi0 and fcoe hangs because FireWire can be used as an ethernet device.

Boot+install (using basic video driver) with a DVD composed by me from rawhide last week (Thursday?), with kernel-PAE-2.6.31-0.180.rc7.git4.fc12.i686.rpm, succeeds.  So perhaps the original problem is no longer interesting.

Comment 8 John Reiser 2009-10-31 01:48:00 UTC
Works for me with a DVD of yesterday's rawhide (Thurs. 2009-10-29):
Successful boot and graphical install from DVD on Apple Mac mini i686 with Intel GMA 950 graphics.
