Hi Stephane,

I ran this problem past one of our kernel guys and he suggested I remove 
the "quiet" option to the console line.  This didn't appear to show 
anything interesting except that the system was unable to find any volumes 
on the disk.  I tried using a bare 2.6.26-rc1 kernel (w/o perfmon2), and 
it does the same thing.  So it would appear that there's something wrong 
with 2.6.26-rc1 for my platform at least.  We're still looking into it, 
but it might be some time before I can verify whether your new kernel 
works.  I can verify that it builds fine, though.

Regards,

- Corey
