I'm not sure if this is the right list, but I'll post here anyway as it is not a user or config issue associated with FC3 operation and 2.6.10 kernels are kind of FC4 stuff ? Anyway... the 2.6.10-1.737 smp kernel is NOT stable on my laptop. It does a hard kernel crash (ie total machine lockup, cannot start a new session). This has happened 3x when websurfing with Konqueror. It seems to occur when performing socket communications ie immediately after double clicking a link, but that is just a quick observation. I've run 2.6.10-1.727 since it became available on the same machine without any issues. I've reverted back to it. Hope this helps. -- Kim Lux, Diesel Research Inc.
