With FC4, kernel upgrade - was OK up to 2.6.15.1.1831_FC4 - lead to a kernel panic since 2.6.15.1.1833_FC4 (with 3 different kernels) With FC5: - I can boot with the original kernel (2.6.15.1.2054_FC5) - Any kernel upgrade lead to the same kernel panic (2.6.16.1.2080_FC5) Kernel panic is: uncompressing linux...OK, booting the kernel Red Hat nash version 4.2.15 starting EXT3-fs: unrecognized mount option "auto" or missing value mount: error 22 mounting ext3 ERROR opening /dev/console!!!!2 error dup2' ing fd of 0 to 0 error dup2' ing fd of 0 to 1 error dup2' ing fd of 0 to 2 switchroot: mount failed: 22 kernel panic - not syncing: attempted to kill init! Any idea?
