I am not convinced that you have found the root cause for this problem.
Enabling "tricky PCI acceleration features" may make the system more
susceptible to this issue, but I see no reason to believe that this is the
source of the problem.
My system is built around an Intel L440GX+ motherboard, and has only
one expansion card: an Intel PCI NIC to provide a network interface in
addition to the on-board LAN. Intel motherboards are known for their
conservatism and stability, particularly in the server and workstation
lines. There are no options in the BIOS for "PCI acceleration" or other
envelope-pushing system tuning.
And, there is still the issue that this device timeout problem first
became noticeable in 4.6-RELEASE, on the same hardware configuration.
Now, as per my reports in the PR, this problem was _alleviated_ by
something in 4.6.2-RELEASE (the frequency of occurance is much lower),
but it most definitely has not gone away.
Cheers,
John
