Get machine to boot from SW RAID
OK, figured out how to get the stabilized line in. I'm trying to boot from a SW RAID, and keep getting a kernel panic, with my kernel 22.214.171.124 build (selected this kernel since we are using it on another machine here). My kernel 2.6.18 build will boot with the RAID and works fine. I've compared the initrd*.img files, and the only differences now between the working and non-working version is the following lines are included in the working version:
echo "Loading dm-mem-cache.ko module"
echo "Loading dm-region_hash.ko module"
echo "Loading dm-message.ko module"
echo "Loading dm-raid45.ko module"
In the menuconfig, the "RAID 4/5 target (EXPERIMENTAL)" option is not available in the later kernel version. Otherwise, all my "multi-device support" options are set the same (although there is an option in the newer kernel for "Device mapper debugging support").
I'm running RAID 1, so it doesn't seem like the raid45 module is important, but it seems like the others must be the cause of this issue.
Anyone have an idea of how I can get this puppy running? Do I need a newer (or older) version of the kernel? Ultimately, we're trying to collect data with a firewire camera, and this has driven the change to the newer (unsupported by Red Hat) kernel.
