I'm triggering this BUG_ON during boot, which happens while freeing initrd
memory:
EIP is at free_init_pages+0x37/0xac
[<c01143f1>] free_initrd_mem+0x11/0x13
[<c03ce259>] free_initrd+0x13/0x29
[<c03cf647>] populate_rootfs+0xdc/0xe2
[<c01003af>] init+0x42/0x253
[<c0103bbb>] kernel_thread_helper+0x7/0x10
I'm not sure why this memory isn't aligned now.
The patch below allows my system to boot. Any clues about the correct fix
appreciated.
