[Bug 1047531] Re: Ubuntu 12.04 (Precise) guests can't boot on Ubuntu 10.04 (Lucid) QEMU-KVM host

[Serge Hallyn]

Peeking through gdb, it seems the kernel is hung inside setup_arch:


#0  0xc0135e81 in ?? ()
#1  0xc097a0a3 in ?? ()
#2  0xc09744ed in ?? ()
#3  0xc09740ba in ?? ()
#4  0x00000000 in ?? ()

where System.map (in the precise image) shows


c097a024 T reserve_standard_io_resources
c097a048 T setup_arch
c097a756 T i386_reserve_resources

and


c0135e50 t native_flush_tlb
c0135e60 t native_flush_tlb_global
c0135e90 t native_flush_tlb_single
