Not much to go on here, but I've seen apparently severe brain damage
caused by problems with interrupt allocation changes between kernels:
once that was resolved the issues went away.  So I think especially
since there isn't much else to try, I would hit 'A' at the grub boot
menu, and append stuff like

acpi=noirq

and

pci=biosirq

to the kernel commandline.  They won't help if the actual problem is
elsewhere but it's worth a go.  Even

acpi=off

might be worth it just as a test.
