[Bug 599196] Re: ATI Video output cuts off completely during boot for several seconds

[Luke]

With Kernel 2.6.35-7.12 the forced VGA workaround does not work, nor
does another workaround that functioned with an earlier version of
kernel 2.6.35-7-generic. It seems that with all versions of 2.6.35, the
PREVIOUS boot must be one that did not involve a video output
cutoff(however short) on starting the root filesystem init. Behavior is
quite inconsistant as updates to other packages come through, with the
latest initramfs-tools update killing the forced vga workaround in
2.6.35-6-generic, for instance. I rolled initramfs-tools back for that
kernel, which I now use, and tried 2.6.35-7.12 both ways, with and
without vga=0x365 on the grub command line, after booting the Lucid
kernel for a clean previous boot, but nothing worked.

With 2.6.35-6, the video output cuts off without the forced vga. With
the first version of 2.6.35-7, this was not needed, but the update to
2.6.35-7.12 seems to have killed all the workarounds. Been doing a lot
of experimenting trying to find out exactly what in the init sequence is
triggering this, have confirmed mountall's connection to plymouth is not
at fault by temporarily substituting a script.
