Boot hangs with Debian Jessie on Toshiba Satellite C55-A
I have a brand new Toshiba Satellite C55-A-1ND. I have installed it so
that it dual-boots Win8 and Debian (this was an adventure in itself).
The problem is that I cannot get Jessie to boot. It just seems to hang
after: "Loading initial ramdisk".
Here are the things I tried so far:
* It's not a secureboot/fastboot/UEFI thing. Secureboot and fastboot are
off and I got Grub EFI running.
* Grub is able to find the bootfiles. When I go to grub console and
enter the startup commands manually, the vmlinuz in initrd files are
found. I also get no errors after loading them. Here's the list of
commands I execute:
linux /boot/vmlinuz-3.14-1-amd64 root=/dev/sda7 ro
During this process I get no errors. After 'boot' it just seems to hang.
* Adding nomodeset or xforcevesa as boot parameters doesn't help
* Updating initrd (update-initramfs -u) doesn't help
* Thinking it may be a graphics issue (e.g. system boots, I just don't
see it) made me try installing the proprietary nvidia graphics drivers.
* Someone on #debian-next said my system was an optimus-based system, so
In installed bubmlebee-nvidia and primus. No effect.
The strange thing is that the jessie netinst CD works just fine. I can
boot it in both text as graphics mode and use it to install jessie and
to enter rescue mode.
I am all out of ideas. Can someone help me figure out what is wrong?
