5 Why? Is it because it couldn't find your root device? Did it detect
6 your hard drives correctly on boot? Or was it because it found your
7 root, but failed to mount it? Or is it something completely unrelated
8 to mounting root?

10 The specific panic message is significant here if you expect us to help you.

15 No, you posted the *one line* from your dmesg that indicated that you
16 were booting from the wrong kernel. That was even before you made the
17 claim that you were running the old kernel, but somehow booting from
18 the new kernel, which was the message that I was replying to. The
19 dmesg output would have confirmed or contradicted that claim, and the
20 single line you posted earlier had nothing to do with verifying the
21 kernel version you booted from.
22
23 FYI, one of the first things the kernel does when it boots is to log
24 essentially the same information as uname produces. It does this
25 before initializing devices, mounting filesystems, or much of anything
26 else. It also shows up in /var/log/messages to, and looks something
27 like this:
28
29 Linux version 2.6.16-suspend2-r5 (root@carcharias) (gcc version 3.4.6
30 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)) #25 SMP Sun May 14
31 03:19:08 MST 2006
32
33 The above tells you a lot...that I compiled my kernel at 03:19 on May
34 14th. It also tells you that was the 25th time I compiled this kernel
35 version. I was obviously up late trying a few things! :-)
36
37 So if you do a "dmesg | grep 'Linux version' ; uname -a", and they
38 somehow report different things, then what you claimed could be true.
39
40 Now to be fair I did not actually ask you to post your dmesg output.
41 I asked how you checked that you were booting the new kernel, and
42 suggested that checking dmesg output would be the best. Of course, if
43 you did not know what to look for there, posting the output would have
44 been fine.
