Arnd? > Good idea. I checked the patch against the failed randconfig, and must unfortunately report that it does not fix the problem. I'm attaching the .config to this email. Two things to note: - this is building for mach-rpc, so CONFIG_CPU_32v3 is enabled, and presumably this is required for reproducing the problem, while building for ARMv4 as I previously said in error does not cause the problem. - I have verified that CONFIG_VDSO is disabled here, but the file is still getting compiled.
