grub hangs after boot command, before unpacking kernel

[Jan Lenaerts]

hello, 

I used grub without a problem, it worked before with all kernels, but
now sudden grub hangs after the boot command, there is no error
message, the only thing on screen are the executed boot commands. 
I have 3 kernels defined in my grub, debian 2.6.14 , debian 2.4.x and
ubuntu 2.6.12, the last two boot without a problem but the debian 2.6
hangs, I tryed to install different 2.6 debian kernels(386,686) but
they all fail, my device.map and grub config is correct. Tryed to
mannualy boot the kernel but then it also hangs, tryed to regenerate
the device.map but still no solution. after 3 hours searching I am out
of options.

has anyone an idea what else I can try? or what the solution is.

Thanks in advance,
Jan lenaerst
