"acpi=force init=/bin/bash noapic " results in neither acpi=force nor noapic being used.

https://bugzilla.novell.com/show_bug.cgi?id=246466 ------- Comment #7 from bwalle@novell.com 2007-02-18 10:38 MST ------- The command line patches didn't change the parsing of the command line. Only the way it's stored. So if your system boots and /proc/cmdline is right, I think the problem are not the commandline patches. However, I can build a kernel image of HEAD without that patches to verify and/or take a look at that problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

As long as this does not happen on a normal system...

It looks like a timing issue / race condition, but it could also be a plain bug in QEMU.

If I have some time left, I could take a look at this (but only the latest and greatest kernel, not SP1 since we don't support QEmu AFAIK).
