[Qemu-devel] [Bug 942299] [NEW] Regression in booting HelenOS/ppc under Qemu

[Jakub Jermar]

Public bug reported:

Mark Cave-Ayland identified Qemu commit
41557447d30eeb944e42069513df13585f5e6c7f as the first bad commit which
prevents HelenOS/ppc from booting with OpenBIOS taken from Qemu 0.11.1.
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.
