bootmanager hangs

[cheesie]

having installed the alpha version for a second time, I got a small problem: The bootloader starts but doesn't load the default entry. I have to press "enter".

BTW. I use the third mentioned linux kernel because the WLAN (D-Link Router) doesn't work with the newest kernel version. (Linux starts with a Bug kernel message)
