Hi Paul, I've tried to compile BLCR 0.8.2 for vanilla 22.214.171.124 with the two patches you've suggested to Neal, but I've got the same configure error as him, i.e. checking for Linux kernel symbol table... failed configure: error: Failed to locate kernel symbol table. Try using --with-system-map or --with-vmlinux. When I add an option --with-system-map, the error message is: checking for Linux kernel symbol table... failed configure: error: Failed to validate "/usr/src/kernels/linux-126.96.36.199/System.map" Would it be possible to try your patches for 2.6.33?
