Kernel hang issue "All ACPI Tables successfully acquired"

[Ajoy Das]

Hi

I am running coreboot on qemu with the following sequence.

coreboot -> seabios -> GRUB -> kernel.

The kernel booting hangs at *All ACPI Tables successfully acquired*

coreboot-4.0
kernel 3.19

when I pass acpi=off to the kernel command line parameter the kernel boots
fine in this scenario.

Is there any specific coreboot option is there to be enabled for successful
booting.
or anyone knows of this issue.

please help

Thanks
