Re: How do you fix a Kernel Panic?

[Don MacAskill <onethumb onethumb com>]

For some reason, the ia64 and x86_64 kernels don't have netconsole 
compiled as a module, making it tough to netdump:

[root zeus configs]# pwd
/usr/src/linux-2.4.21-15.EL/configs
[root zeus configs]# grep NETCONSOLE *

I'm currently buliding the x86_64 module myself, I'll see how it goes, 
but I have consistent crashing with x86_64 WS every 8 days or so.

Anyone know why those platforms don't have NETCONSOLE by default?  ppc64 
does, so I don't think it's a 64bit thing.
