Ok, the kernel compiled with gcc version 3.2.1 20021207 (Red Hat Linux 8.0 3.2.1-2) has now been up for more than a week. It seems stable, but I'm not sure yet. Which brings me to the question: which gcc version is considered most stable for compiling 2.4.x these days? README says: "Make sure you have gcc 2.95.3 available. gcc 2.91.66 (egcs-1.1.2) may also work but is not as safe, and *gcc 2.7.2.3 is no longer supported*" And Documentation/Changes says: "You may use gcc 3.0.x instead if you wish, although it may cause problems. Later versions of gcc have not received much testing for Linux kernel compilation, and there are almost certainly bugs (mainly, but not exclusively, in the kernel) that will need to be fixed in order to use these compilers." and "The Red Hat gcc 2.96 compiler subtree can also be used to build this tree. You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build the kernel correctly." This seems to suggest 2.96-85 would be more stable than gcc-3.2.1-2.

I guess I'll poll Justin when/if the aic7xxx crashes reappear. The hang was probably not related to aic7xxx.
