Here is what happens when I try to run kernel-2.6.18-1.2868.fc6 which I updated using SMART. This is a desktop PC.
ACPI: Getting cpuindex for acpiid 0x1
ACPI: Getting cpuindex for acpiid 0x2
ACPI: Getting cpuindex for acpiid 0x3
Red Hat Nash version 126.96.36.199.2 starting
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
ERROR opening /dev/console
Trying to use fd 0 instead
WARNING: can't access (null)
exec of init ((null)) failed!!! Bad Address
Kernel panic - not syncing: Attempted to kill init
Kernel 2849 still works without issue
Also why is it that SMART doesn't delete the kernel that yum normally would?
