I've just upgraded my FC5 system using yum (normal FC5 system, installed from DVD) and I now get a kernel panic 2.6.17-1.2174_FC5 in insmod after trying to load ext3.ko (or maybe ext.ko) and the system won't boot with the new kernel.
Platform is x86_64 SMP (AMD4200+) on an Nvidia NFORCE 4 motherboard with SATA (not raid) disc. I am running the 64-bit kernel.
Booting from the previous kernel [ 2.6.17-1.2157_FC5] is fine.
I thought I'd let you know as I've never had a non bootable kernel from yum before.
Also, this leaves me in an awkward situation. In FC5, yum only persists one previous kernel version, so if I update the kernel via yum again it will remove 2.6.17-1.2157_FC5 which is fine and leave 2.6.17-1.2174_FC5 which doesn't boot. So, if the next kernel doesn't boot on my machine it's bye bye linux. Is there any way that I can modify yum so that it stores more than two previous kernel versions? I won't feel safe upgrading until I can do this.
