Toshiba Satellite P55 laptop fails to transition from Grub to Linux
Last modified: 2013-10-08 12:18:04 EDT
Description of problem:
A Toshiba P55t-A5202 laptop (not to be confused with the P55 Intel chipset; this series has units labelled P55 & P55t) fails to boot Fedora 19. I have tried both USB and CD-ROM installs.
This is an UEFI laptop; but disabling secure boot does not help.
How reproducible: Always
Steps to Reproduce:
1. Boot a Fedora LiveCD or Live USB stick by holding F12 during startup to choose an alternate boot device.
2. Grub will start; edit grub settings as desired.
3. Select a boot option and let grub do it's thing.
Failure to boot after the grub countdown completes or a boot option is selected. Grub will tell you that the binary to boot has a valid signature (secure boot enabled) or that secure boot is disabled. But without grub debugging turned on this is all that is seen, even when "quiet and rhgb" is removed.
If Grub debugging is turned on a lot of malloc messages are displayed which seem related to reading from USB and/or parsing the boot command list. However at least with the CD-ROM it is implied that Grub closes the CD-ROM device near the end of these messages.
Linux kernel boots and Fedora' installer or Live environment starts.
Adding "nomodeset" and/or "i915.enable=0" as suggested at http://askubuntu.com/questions/326192/laptop-boots-to-black-screen-on-13-04-but-works-when-an-external-monitor-is-plu does not help.
I personally know how to reach the grub commandline; but do not know enough about early debugging to figure this out.
