kernel panic under 2.6.2-rc1-mm2

kernel panic under 2.6.2-rc1-mm2

[Jim Faulkner]

2.6.2-rc1-mm2 kernel panics on my machine.  I believe that it is related
to software RAID based on the kernel output.

Unfortunately I do not have the complete output since it locked up at boot
time.  The kernel panic output ran off the screen.  Below is what was on
my screen from top to bottom (minus alot of numbers), and below that is my
current /proc/mdstat and /etc/raidtab.

thanks,

And is 2.6.2-rc1 OK?

Yes, 2.6.2-rc1 works fine.

2.6.2-rc1-mm1 works fine as well, however under that version I am still
getting the non-fatal kernel bug which I mentioned a few days ago:

eek, don't trim emails that much: it sends me into cognitive panic trying
to remember which of the past week's 7,000 email dicussions this pertains
to.

Ah-heh.  The md-* patches which were recently added to -mm might be bad,
yes?

Actually you were the one to trim the e-mail in your response. :)  I'll
make sure its clear what I'm talking about next time that happens.

Included below is my entire original e-mail.

Looks like it to me.
