    hammer - HAMMER Version 7

intermittent boot hangs stopping at

ums0: <Logitech USB-PS2 Optical Mouse, class 0/0, rev 2.00/20.00, addr 5> on usb
ums0: 3 buttons and [XYX] coordinates ID=0
no B_DEVMAGIC (bootdev=0)

Boot proceeds normally when using verbose option which is why I can attach
the verbose dmesg.

The machine uses a refurbished Asus P8H77-V motherboard with several
internal hard drives with different OSes using legacy BIOS.
