I update this box about once a week, that previous kernel was from Jun 11. and that still rebooted successfully. As the kernel from June 18. is now kernel.old I don't know the SVN rev for the June 11 kernel, but it looks like it was broken between June 11. and 18. However my workstation, also running a kernel from June 18. does still reboot OK, it's using ahci and UFS. Florian
