I didn't do anything different from what I usually do. This happened while I started a cross-compilation of a kernel for ARM. I had been running this kernel for about 8 days without a problem, until this happened. -- Cheers, Luca. -- To unsubscribe from this list: send the line "unsubscribe ecryptfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
