Comment (by [EMAIL PROTECTED]):
... and i'm testing it ;-)
The older HAL's doesn't work on this platform, since they insist on doing
byteswapping on some registers. The new HAL uses external write functions,
which allows me to disable the byteswapping.
Here is the promissed complete oops. Turned out that i didn't need
ksymoops at all. Just building the kernel with full debugging was enough:
