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.
