Message-ID: <4DD41613.4040102@unsolicited.net> Date: Wed, 18 May 2011 19:55:15 +0100 From: David <david@...olicited.net> To: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: Latest kernel fails to build multi-threaded on ecryptfs home I'm seeing some unpleasant things when building multithreaded when running the latest kernels. The compiler complains of truncated files and implausible characters. Single threaded builds seem fine. This seems to be connected with the following errors in dmesg :- [ 4421.923887] ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4] [ 4421.923898] ecryptfs_readpage: Error decrypting page;
