Hello Karel,

To apply the patch I have to install it manually, without rsb.Unfortunately I encountered a problem with undefinded

symbols.

Here are my steps to create the bsp:

git clone https://github.com/RTEMS/rtems-source-builder.git
mv rtems-source-builder rsb
cd rsb
git checkout 5
cd rtems
../source-builder/sb-set-builder --prefix=$HOME/DBG/rtems5 5/rtems-i386
cd ../..
git clone https://github.com/RTEMS/rtems.git
cd rtems
git checkout 5
./rtems-bootstrap
cd ..
mkdir build
cd build/
mkdir b-pc686
cd b-pc686/

../../rtems/configure --target=i386-rtems5 --prefix=$HOME/DBG/rtems5--disable-networking --enable-posix --enable-cxx --enable-tests--enable-rtemsbsp=pc686

make all
make install
cd ../..
git clone https://github.com/RTEMS/rtems-libbsd.git
cd rtems-libbsd/
git checkout 5
git submodule init
git submodule update rtems_waf

./waf configure --prefix=$HOME/DBG/rtems5 --rtems-bsps=i386/pc686--buildset=buildset/default.ini

./waf

Could you be so kind and test attached patch? It basically reverses
priority of PCI accessors and helps a lot my Thinkpad T400/T500 where

BIOS accessors are slow and I/O are fast. I've been hit by the issuenoton network, but while BSP tries to initialize its console -- it triesto

find all the possible PCI UARTs and this hurt time-wise a lot.

Please report if this helps or not. I've not submitted the patch as all
my other machines do not provide PCI BIOS in RTEMS friendly way and
RTEMS is using PCI I/O accessors by default on them -- so speed access.

I've neither tested on qemu with nic so your report will be appreciated
here.

Thanks,

I have a problem with rtems_bsd_initialize() in POSIX_Init() and qemu.

call of
    sc = rtems_bsd_initialize();
    assert(sc == RTEMS_SUCCESSFUL);
always takes about 45 seconds until it is finished.

The output of

comes very fast, but then the system is "frozen" for about 45 seconds.
Then this output appears:

The setting of
    default_network_set_self_prio(RTEMS_MAXIMUM_PRIORITY - 1U);
seems to have no influence. I also did not understand the setting of
priorities.
