Subject: Microblaze image hanging in qemu with 3.15-rc
Date: Tue, 22 Apr 2014 10:23:56 -0700 [thread overview]
Message-ID: <20140422172356.GA15672@roeck-us.net> (raw)
Hi all,
when trying to run a microblaze image with 3.15-rc1 or 3.15-rc2 in qemu,
I get the following hangup. This used to work with earlier kernels
with the same configuration.
Is this a known problem, or is something wrong with my configuration
or with my qemu command line ?
Thanks,
Guenter

The image hangs here, and I have to kill qemu to get out.
