If we leave out the HV case, it's almost always 0. To reflect this, let's redesign the way that MSR value gets calculated. Using this, we also squash the bug where MSR_POW can slip through into the interrupt handler MSR. Reported-by: Thomas Monjalon Signed-off-by: Alexander Graf Signed-off-by: Edgar E.

Note that we deliberately use the OpenBIOS from Qemu 0.11.1 because there is another suspected, unrelated bug in newer versions of OpenBIOS. For reproducing purposes, the following HelenOS image can be used (latest HelenOS exhibits the same behavior): http://www.helenos.org/releases/HelenOS-0.4.2-ppc32.iso Commit 41557447d30eeb944e42069513df13585f5e6c7f will result in HelenOS not making any further progress after it prints "init: Spawning /srv/devfs". The previous commit, f844c817d726cd2bdb431aa41c8217891ede2eaf, works fine - HelenOS will spawn a couple of shell instances and will be accepting user input.
