[Cbe-oss-dev] PS3 boot game os flag no longer honoured

[Grant Ferley]

Thanks for the reply Geert.  After being set in 2.16.22-rc3, the kboot
prompt reports that the boot flag is indeed set to 0 (boot game os) when
other-os-flash-util -s /dev/sdb is executed.  Running boot-game-os from the
kboot prompt does work correctly as it always has.

However, if the system is powered off (shutdown from Linux to runlevel 0
hangs and the unit needs to be manually powered off), the game OS loads when
turned back on.  It would appear then that there is something not happening
right when newer kernels are shutdown to runlevels 0 and 6, perhaps.

That's strange... I'll take a look at it tomorrow. While I don't boot to
GameOS
regularly, it did work last time I tried.

Does other-os-flash-util on kernel 2.6.16 (e.g. your kboot bootloader
kernel,
if you still use the original one?) report the flag is set?

/dev/ps3flash is indeed the correct device to use with other-os-flash-util
on
recent kernels.
