No, but I think booting with extensions off might have fixed it.

On the LC III, the new kernel (compressed and uncompressed) hangs
consistently at the ABCFGHIJK screen. I tried increasing Penguin's
memory to 34000, still hangs. Adding earlyprintk as an option also
didn't work, there are a few lines after ABCFGHIJK, then it stops:
ABCFGHIJK
