Public bug reported:
While trying to fix Bug #1432659, I updated the HP Pavilion 13-b208tu
bios to the latest available on the HP website (F.26). After the update,
the laptop no longer boots Ubuntu 14.10 or Ubuntu 15.04 (Ubuntu 15.04
from the hard drive, Ubuntu 14.10 using a LiveCD). The grub menu is
available and works, the kernel loads, the initrd step works, and then
it hangs hard and requires power cycling.
The required information for a kernel bug report can be found in Bug
#1432659, from the original shipped F.23 bios. I obviously can't attach
information with the F.26 bios loaded.
I can confirm that the bios update worked, and I have repeated it twice.
HP diagnostics give the system a green light, and I can boot to FreeDOS
as normal. I'll leave the system unbootable with the F.26 bios for a
while in case someone can help me diagnose further from grub.
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Incomplete
** Package changed: bcmwl (Ubuntu) => linux (Ubuntu)
