Hello, Hackers. I've upgraded my fileserver to 10-STABLE and got very strange (but very-very painful) problem, which I could not reproduce on virtual machine (VirtualBox). I'm using geom_raid5 module (and I'm its maintainer, yes) and module, built for 10-STABLE (after world & kernel build & install & reboot), and loaded via /boot/loader.conf is reason to almost instant crash after boot. Sometimes system mounts filesystems before crash and sometimes not. Most of time it is "page write: page not present", in different places. PS/2 keyboard is always blocked after that, I could not drop to debugger. No memory dump performed. Several times it turend off video output (!) right after crash. But if I boot without this module, drop to single-user mode, load module with kldload and continue booting with "exit" everything work smoothly for hours! I understand, that it it some incompatibility between module new kernel, but I could not reproduce it on VirtualBox instance, and I'm puzzled, that this crash does not occur if module loaded by kldload! Maybe, here is some hint in this? -- // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
