I attached the patch which I used to revert commit 4d14a459857bd151ecbd14bcd37b4628da00792b I did a split of this patch, and build kernels with only the memcpy or only the memset part reverted. They both segfault. memset reverted =============== [ 11.129998] VFS: Mounted root (ext3 filesystem) readonly on device 8:20.
