I have a machine that is running Red Hat 9, and trying to run the 2.2b for kernel 2.4 causes an 0x2 error in BOINC/S@H, and checking on the errored result shows that the 2.2b app couldn't be found, even though it's where it should be. The processor is an AMD Duron 1000MHz w/SSE and 3DNOW capabilities. The glibc that is installed on the system is glibc2.3.2.
