This is a bit weird, as the hw-platform, apparently is i386 or i686, not sure, but the cpu is definitely accessible in /proc/cpuinfo.
The following text is from the sysctl call in the kernel help text for the option: CONFIG_SYSCTL_SYSCALL: sys_sysctl uses binary paths that have been found challenging to properly maintain and use. The interface in /proc/sys using paths with ascii names is now the primary path to this information. Apparently my copy of uname is still using the sysctl call(or trying to), as it comes up with 'unknown' for -p, --processor print the processor type or "unknown" -i, --hardware-platform print the hardware platform or "unknown" This appears to come from: uname (GNU coreutils) 8.26.18-5e871 Is this fixed in a newer version? Thanks.
