Hi, Jifl,

Do you ever meet following errors when you run pci1.exe test, following is
what I met even I use the most updated cvs release, it is the same as
before. The PCI bus scan failed for a SIGBUS bus error...Could you please
take a look? Thanks!

Regards,
-Ling

[New thread 3]

Program received signal SIGBUS, Bus error.
[Switching to thread 3]
warning: Warning: GDB can't find the start of the function at 0x80104820.

    GDB is unable to find the start of the function at 0x80104820
and thus can't determine the size of that function's stack frame.
This means that GDB may be unable to access that stack frame, or
the frames below it.
    This problem is most likely caused by an invalid program counter or
stack pointer.
    However, if you think GDB should simply search farther back
from 0x80104820 for code which looks like the beginning of a
function, you can increase the range of the search using the `set
heuristic-fence-post' command.
