Thanks.  But can you please attach the output of "lspci -vvxxx" (not
"-vxxxx") for the entire system before the problem occurs?  All the
info is in the "-xxxx" output, but it's really painful to decode it
all by hand.  Using "-vv" will decode the PCIe Capability structures
where the ASPM configuration is.  And the entire system is
interesting, because ASPM requires configuration on upstream bridges
as well as on the device itself.

My only guess is that there's something wrong with the ASPM
configuration and the device just stops responding to config accesses
(and probably MMIO accesses, too, based on the errors in your dmesg
log).  Or maybe the device got powered off somehow.
