+on single core Raspberry Pi, qemu-system-sparc appears to hang in bios
+Description of problem:
+I suspect it to be a race condition related to running on the slow single core Raspberry Pi, as I haven't managed to reproduce on x86 even when using taskset to tie qemu to a single core.
+
+The problem occurs about 4 out of 5 runs on qemu 5.2 (raspbian bullseye) and so far 100% of the time on qemu 6.1.
+
+About five seconds after start the sparc bios gets as far as `ttya initialized` and then appears to hang indefinitely.
+
+Instead, it should continue after about 3 more seconds with:
+```
+Probing Memory Bank #0 32 Megabytes
+Probing Memory Bank #1 Nothing there
+Probing Memory Bank #2 Nothing there
+Probing Memory Bank #3 Nothing there
+```
+
+See below for workaround.
+Steps to reproduce:
+1. Need a single core Raspberry Pi running raspbian, such as Raspberry Pi 1 or Zero
+2. Download ss5.bin from https://github.com/andarazoroflove/sparc/raw/master/ss5.bin
+3. Run the command:
+```
+qemu-system-sparc -m 32 -bios ss5.bin -nographic
+```
+After about 5 seconds of output it hangs at `ttya initialized`
