My test lab now features about 75 flavors of Unix on multiple CPU types. Today, I got successful builds and validations on 69 of them, and I'm now examining the failures.
The first failing machine is our ArchLinux 4.2.3-1-ARCH system, for which "cat /proc/cpuinfo" reports processor : 0 model name : ARMv7 Processor rev 10 (v7l) BogoMIPS : 7.54 Features : half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpd32 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x2 CPU part : 0xc09 CPU revision : 10 ...
