I managed to write some of the dump.

here it is:

***********************
uncompressing linux...Ok, booting the kernel
Red Hast nash version 6.0.19 starting
BUG: unable to handle kernel NULL pointer dereference at virtual
address 00000024
printing eip: c04b93d5 *pde = 77e2c067
modules linked in: sata_sil libata sd_mod scsi_mod ext3 jbd mbcache
uhci_hcd ohci_hcd ehci_hcd

*****************************
then the boot stops. However if I press ctrl-alt-del I get:
md: stopping all devices..

and then my laptop reboots.

thanks,
