Re: grub_machine_fini on efi systems

[Peter Cros]

There is also a problem with Apple 64 bit grub.efi booting ubuntu 2.6.27 linux in which the kernel is booted and starting but all video is lost after the boot command. I don't know if there may be a connection.

 A temporary fix is to change Video frame buufer settings in /loader/i386/efi/linux.c: 

grub_find_video_card and grub_linux_setup_video 

Then proceeds to the next bug (libata hangup during initrd ).

Hello. I found a serious problem which may be the cause of linux not booting on some efi systems. grub_machine_fini is called before grub_linux_boot. grub_machine_fini returns all memory allocated by grub2 to efi. This includes all memory used to load modules. So actually efi can rightfully destroy linux module before it has slightest chance to do its job. I asked step21 to declare linux boot as returnable to stop grub_machine_fini. However it's nothing more then a workaround. I hope that someone will find a way to fix this nicely because for the moment I see none. (perhaps tomorrow I'll find sth)
