HelenOS/ppc32 non-debug does not boot (in Qemu)

HelenOS/ppc32 non-debug does not boot (in Qemu).
The last displayed message is the loader's:

Booting the kernle…

The debug version boots fine.

Interestingly enough, I can reproduce this only on my iBook G4 where I have a different version of Qemu. Trying to achieve the same on my Ubuntu desktop does not produce the desired result.

The problem seems to be specific for Qemu version 0.9.0. Version 0.10.5 does not have this problem. Yesterday I checked that the iBook G4 continues to boot non-debug HelenOS without any problems.

Looks like we can defer this until 0.5.0.

Tested non-debug mainline build with Qemu 0.11.1 and found no problems.
I am thus closing the ticket as worksforme.

This is mostly unusual. The kernel ppc32 code is currently heavily broken and even made deliberately unbootable in the process of rewriting. It is probably not related to the original cause of this ticket, but the final result should be the same: It should not actually boot

I am reopening the ticket for the time being to keep a track of the ppc32 rewrite.

Hi Martin,

see #243 which tracks the critical bug in the ppc32 exception handling. The problem described by this ticket does not exist. Moreover, the non-debug kernel boots just fine. Just give it a try and then please reclose this ticket.

Thanks,
Jakub

Anyway, going ahead and reclosing this ticket.
The ppc32 exception handling issue is tracked by ticket #243.
