If you're using a distribution that sets a booting script (e.g. Ubuntu,
Fedora) disable that (remove splash from line in grub, I think) and also
remove the quiet option while you're at it.
If the machine is rebooting straight away after a panic, set panic=30 as a
boot option.
You may also get more information if you put debug as an option.
Try these options by edit the config in grub at boot time first to make
sure they don't stop the system booting completely. If that works ok make
them a perminant changes in grub. e.g for Ubuntu:

Edit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="panic=30 debug"

# sudo update-grub
