Here it doesn't work with linux 2.6.13. Is there a special configuration

Hi!
I've some problems with qemu-system-sparc and programs using floating point
instructions. Each time at least two floating point programs are started in
qemu simultaneously, one or both are killed by the linux kernel with a SIGSEV
signal (sometimes because of a corrupted stack or invalid reg

The attached patch is an updated version of your patch. With whis patch I was

Today I did some more tests to determine, what's going wrong. At first, Linux

Hi!
I still have problems when using a disk image for the SPARC system emulator.
Reading and writing now works better than in previous versions, but sometimes
data written to image is simply corrupt. To find this problem I wrote a small
