Hi Adrian,

Testing with real hardware is very cool! Maybe I will get some SH
hardware myself one day. For now you've motivated me to do a QEMU SuperH
fork with more features, with a lot of help from my LLM agent:

https://github.com/kmehltretter82/qemu-superh

I will send some bug fix patches based on it soon, hopefully also fixing
your 6.5 problem. I believe it is an old heap overflow in the SH intc
code that only started to crash when sh7785lcr_defconfig switched from
SLAB to SLUB in 6.5.
