Bug 679394

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information especially concerning your hardware we require that will be helpful in our diagnosis of this issue.

If the computer is not completely frozen when installation fails, switch to the console (Ctrl+Alt+F2) and copy /tmp/X* and /var/log/anaconda.xlog to some other place -- USB stick, some other computer via network, somewhere on the Internet, and please attach it to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

If the computer is completely useless after installation fails, you can also install Fedora with a VESA mode driver (see http://docs.fedoraproject.org/en-US/Fedora/13/html/Installation_Guide/
for more information on that). Then after successful installation you can collect /var/log/anaconda.xlog, /var/log/Xorg.0.log, and the output of the program dmesg instead.

Or you can install Fedora in a text mode completely, and then start X after that. If it fails, still /var/log/Xorg.0.log and the output of dmesg program from the failed attempt to start X would be useful.

We will review this issue again once you've had a chance to attach this information.

Thank you very much in advance.

Thank you for your work.
Well, my be i'm redundant, but i'd repeat that the problem is present ONLY in EFI mode. Since EFI support isn't mature in fedora, i've been forced to tamper a bit with the install process. First, i installed fedora in BIOS mode, then i compiled GRUB2 from source and installed it in the EFI system partition of my iMac. So now i've a system which starts flawlessly in BIOS mode, but with no X when started in EFI mode. I can reach a root console adding the option 'single' at the end of the grub2 kernel command line. But when in runlevel one, any command like 'X' or 'telinit 5' produces a black screen, regardless of any option i can pass to the kernel when started by grub2.
By the way, i was forgetting! If i don't pass the 'nomodeset' option the screen goes blank from the very first start.
So, for the moment i can attach the requested files for the system, when booted in BIOS mode. If you ever needed the same files with the system booted in EFI mode, please let me know.

Thanks again

Xorg.0.log when started in efi mode

Xorg.0.log when started in efi mode (and kernel option 'video=efifb' passed via the command line)

Well, i re-tested the system in EFI mode. I start the system in single user mode, then i issue the commands 'X --configure' and 'X -config /xorg.conf.new'.
I get the usual blank screen so i hit ctrl-alt-backspace to terminate X and now i have a Xorg.0.log file. Noticeably it contains the following error:


[   401.530] (EE) RADEON(0): V_BIOS address 0xd00 out of range

Please not that before starting the kernel, in grub2, i load the bios as described in the following guide: http://grub.enbug.org/TestingOnMacbook

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please attach (all in EFI mode)

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

xorg.conf

Ok. I'm attaching the xorg.conf file as generated by the "X -confgiure" command (in EFI mode) because, when in BIOS mode i use KMS, hence, have no xorg.conf file.

WOW! Hoorrray for kernel 3.1!
The new kernel (in fedora 15) boots *flawlessly* in EFI mode, even in KMS!
Splash screen, 3d accell. etc.

Great job!

Finally i can use only one boot loader for the whole system!

Thanks

Thank you for letting us know.
