Right after grub loads the kernel, before the "Uncompressing Linux" message is shown, it hangs. The BIOS appears to still be alive (ctrl-alt-del works, keyboard lock LEDs respond). It seems to be caused by the new x86 setup code. My kernel is Linus' git as of a1c582d0720f2eff61043e90711767decf37b917. I bisected and confirmed that 4fd06960f120e02e9abc802a09f9511c400042a5 triggers a non-functioning boot. This system has Dell BIOS rev A38 and a P4 3.2 w/HT. What should I do next to debug this problem? --nFreZHaLTZJo0R7j Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.6 (GNU/Linux) iD8DBQFG13VELYBaX8VDLLURApv0AKDHOZRy7W88qYZ/KzhgDlWfo0j32wCeNwI9 6I04gNGt5YCuo7eHTGgDJz8= =x6hz -----END PGP SIGNATURE----- --nFreZHaLTZJo0R7j--
