Description Dennis Schridde 2012-04-26 20:21:31 UTC 
On Gentoo/Hardened /sys/devices/system/node is only read and traversable (0700) by root, which makes erlexec segfault.

See upstream bugreport [1] and the fix [2], which contains a patch that was included in Erlang 15B01, i.e. dev-lang/erlang-15.2.1.

Same problem can be also cause by enabled http://en.wikibooks.org/wiki/Grsecurity/Appendix/Grsecurity_and_PaX_Configuration_Options#Sysfs.2Fdebugfs_restriction in the kernel. You are unable to run erl vm as non root.
