I have a working SuSE 10.1 system running kernel version 2.6.16.21-0.13. Updating the kernel to 2.6.16.21-0.21 renders the system unbootable. My /boot is /dev/hda1, a resierfs file system on /dev/hda My / is /dev/system/system, a resiferfs file system on top of LVM. The above layout works fine when I boot the machine into the 2.6.16.21-0.13 kernel. However, booting into the 2.6.16.21-0.21 system makes the system complain about not finding device /dev/system/system, and then drops me to a shell prompt without / being mounted. The messages that come across are to the effect of "/dev/system/system does not exist" and "device-mapper: device does not appear to be in the device hash table". With my little knowledge of Linux, I gather this to be an issue with the initrd. I noticed that while booting with the new broken (broken at least for me) kernel, module dm_mod loaded successfully. I understand this to be something needed for lvm. My question at this point is how do I get kernel 2.6.16.21-0.21 to boot and run on this machine on which kernel 2.6.16.21-0.13 runs fine? Thanks in advance for any help, -- --Moby
