Hi,
I have successfully installed a Debian instable on an emulated
SparcStation 5 by QEMU. Globally it works correctly, but I have
experienced a few kernel crashes, due to a problem with the ESP
controller. It seems to occur while writing a high volume of data to
disk, although that not always crash the kernel. Note that I am using
the CVS version of QEMU.
You will find the kernel log below. Does somebody have an idea? I don't
know how to debug such a thing, but I can make some tests if needed.
Thanks,
Aurelien
