I installed the latest Fedora Core 1 errata kernel 2.4.22-1.2138.nptl on an Intel PIII box. I downloaded the files I needed and installed it this way; rpm -Uvh kernel-source-2.4.22-1.2138.nptl.i386.rpm rpm -ivh kernel-2.4.22-1.2138.nptl.i686.rpm rpm -Uvh kernel-doc-2.4.22-1.2138.nptl.i386.rpm After I did "rpm -ivh kernel-2.4.22-1.2138.nptl.i686.rpm" I got this error; umount: /tmp/initrd.mnt.xh1685: device is busy ioctl: LOOP_CLR_FD: Device or resource busy rm: cannot remove directory '/tmp/initrd.mnt.xh1685': Device or resource busy The rpm -ivh came back with 100% completion. Doing a Google search didn't come up with much so I continued on. When I booted from the new kernel, I got these error messages; RAMDISK: Compressed image found at block 0 Freeing initrd memory: 159k freed EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended VFS: Mounted root (ext2 filesystem). VFS: Cannot open root device "LABEL=/" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00 If I use "root=/dev/hda2" in GRUB's kernel line, the server will boot fine. Is this a new change or is it a symptom of the first error message? The kernel 2.4.22-1.2135 and previous ones have no problem with "root=LABEL=/". Any suggestions? Thanks, Frank
