Happily, this seems to fix the problem with the above crash on
2.6.24-rc5-mm1, I've also left the fix in 2.6.24-rc5 and I'll be
testing that in my next reboot. It's looking good!
So, this regression is fixed in 2.6.24-rc5-mm1.
Next, it would be nice to rate limit the "Parity error detected..."
messages from the Symbios driver, I'll see if I can hack something up
in the next day or so.
Thanks,
John
