I've been trying to upgrade my kernel from 2.6.22.14-72.fc6. After some troubles I've made a couple of steps forward, but now I'm stuck.
Symptom of failure in every case is essentially the same; final console messages for latest 2.6.25.20 build, for example, look like this: Write protecting the kernel text: 2836k Write protecting the kernel read-only data: 1124k Red Hat nash version 5.1.19.0.3 starting Mounting proc filesystem Mounting sysfs filesystem Creating /dev Creating initial device nodes Setting up hotplug. Creating block device nodes. Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! Building 2.6.22.19 failed to boot. Adding 'ide0=noprobe' to the boot options made it boot successfully. 2.6.23.17 had the same problem, with the same solution. 2.6.24.7 failed to boot, but 'ide0=noprobe' doesn't help. Adding 'irqpoll' (and not 'ide0=...') gets it to boot but fails to mount other partitions of the boot disk. Changing /etc/fstab to replace all occurrences of 'sda' with 'hda' gets it to boot succesfully and mount the partitions correctly. 2.6.25.20 fails to boot; 'ide0=noprobe' doesn't help, nor does 'irqpoll', nor does either version of /etc/fstab. I've also tried 'pci=routeirq' without success. 2.6.32.3 fails the same as 2.6.25.20, though I've tried fewer variations. (The idea is eventually to get up to "latest stable".) The drives reported by a successful 2.6.24.7 boot are: hda: WDC WD1600JS-08NCB1, ATA DISK drive hdd: HDS728080PLAT20, ATA DISK drive hdc: HL-DT-ST RW/DVD GCC-H20N, ATAPI CD/DVD-ROM drive (in that order). Full dmesg from the latest two successful boots are at: <http://crypt.org/kernel/dmesg-2.6.23.17> <http://crypt.org/kernel/dmesg-2.6.24.7> I've tried to cut the configs down as far as possible, to minimize the changes from one version to the next (and it's always possible I've cut out too much). Successful configs and latest failed attempt for 2.6.25 are at: <http://crypt.org/kernel/config-2.6.23.17> <http://crypt.org/kernel/config-2.6.24.7> <http://crypt.org/kernel/config-2.6.25.20> The two variants of /etc/fstab are: <http://crypt.org/kernel/fstab-sda> <http://crypt.org/kernel/fstab-hda> My PCI device list is: PCI ID Works?

Then just before the interesting part it suddenly speeds up again, even if I hack out the "system_state != SYSTEM_BOOTING" check in boot_delay_msec(). I welcome any suggestions for how to get further, including how to get something useful out of boot_delay.
