Could you also try to boot without acpi ?yes, the kernel panic disapear if i remove the line concerning acpi module in grub.
Does 7.2-4 boot for you ? The most important difference would be different compiler used to compile them.It works fine with 7.2-4
Please, could you try this: have all but acpi.ko from 7.2-5 and overwrite acpi.ko by version from 7.2-4 and try to boot with acpi, of course. Petr
