Dear James Bottomley,
thank you very much for your patch; I have applied it, but it does not
appreciably change things. The messages (as far as I can read it - I'm
still missing the first few lines...) have not changed at all, and
booting still ends up in a kernel panic.
I'd be more than happy to check out additional patches ...
Best wishes and regards,
Ernst
