Yes.

Here is what happens:

Booting (CentOS 2.6.9MHRsmp)' kernel direct mapping nodes[?] up to 10100000000 @ 8000-d000 root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.9MHRsmp ro root=/dev/VolGroup00/LogVol00 rhgb quiet [Linux-bzImage, setup=0x1400, size=0x190795] initrd /initrd-2.6.9MHRsmp.img [Linux-initrd @ 0x3706300, 0x18caf6 bytes]

Then the system halts. I'm using the same config file as the installed CentOS 2.6.9-42.0.3, and here are my /etc/fstab and grub.conf contents:

[root@localhost linux]# cat /etc/fstab # This file is edited by fstab-sync - see 'man fstab-sync' for details /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 /dev/hda /media/cdrecorder auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0 /dev/fd0 /media/floppy auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0

Any hints, suggestions, comments, etc. would be most welcome.

Thanks.

I haven't actually made any changes to the kernel yet - I need a working build, hopefully one that matches my current installation, but a working build to start. (Otherwise I won't know if the kernel I'm running and one I've modified contain anything I don't know about....)

I used the config that the installed version had as my base, and I don't think I changed anything. I ran make menuconfig and set the version to something different, then ran make oldconfig to see what changes were needed (none), then built. In theory, if lvm support was in the installed kernel, it should have built into my new one, right?

Do You have an initrd file for new kernel? If not You should create one with mkinird.
