rtems_bsd_initialize() in POSIX_Init and qemu-system-i386

[junkes]

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

nexus0: <RTEMS Nexus device>
pcib0 pcibus 0 on motherboard
pci0: <PCI bus> on pcib0
pci0: <bridge, HOST-PCI> at device 0.0 (no driver attached)
pci0: <bridge, PCI-ISA> at device 1.0 (no driver attached)
pci0: <mass storage, ATA> at device 1.1 (no driver attached)
pci0: <bridge> at device 1.3 (no driver attached)
pci0: <display, VGA> at device 2.0 (no driver attached)
em0: <Intel(R) PRO/1000 Network Connection> port 0xc000-0xc03f mem 
0xfebc0000-0xfebdffff irq 11 at device 3.0 on pci0

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

info: em0: Ethernet address: 0e:b0:ba:5e:ba:11
cpu0 on motherboard

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.
