Andreas has fixes for these issues?
Not sure, all I know is that
- Andreas has some fixes for Leon in his tree
- Sam is unable to boot mainline in qemu
- There is an unknown set of bugs in sparc32 since it has not
been tested for many years without Andreas' patches
it appears that the qemu developers are still testing the sun4m
model against old Linux and Solaris installations [1], but
failure to run the leon3 model could still be any combination
of kernel, qemu or configuration problems.

Hi all: I'm one of the QEMU sun4m and sun4u maintainers so thought it would be worth
a few comments here.
My SPARC work on QEMU is unsponsored, so of course it is reliant upon me finding time
between work and family to fix various bugs. This means that I simply don't have the
time to constantly build and test the latest kernels: what generally happens is that
someone pings me a regression bug report when something breaks and provides a test
kernel/rootfs for me to look at. In the past both Rob Landley and Guenter Roeck have
often flagged regressions and kindly provided these for me.
Other than that I just assume that everything is still working against the upstream
kernel.
The leon3_generic machine is maintained by different people so I'd suggest contacting
them: see [1] for their contact details. I see there is an avocado boot test for the
leon3_generic machine included within the QEMU source tree, but it uses a
downloadable image of HelenOS rather than Linux.
ATB,
Mark.
