We've used two different kernels, and we're getting a kernel panic on a
Pentium III 700MHz (Coppermine). The same kernels running on Pentium III
600MHz (Katmai) processors works a-ok.
Has anyone else seen this? Any ideas? We do a *lot* of disk I/O, but
using IDE disk. I'm willing to play around a bit on this.
Logs are below.
