Hi Antonio,<br>
<br>
This could be due to a bug in the PCI bus allocation code. <br>
It is worth trying the BIOS given PCI allocation plan instead. For
that, try using the following arguments to PCI in menu.lst<br>
<tt><br>
</tt><tt>modulenounzip /harness/sbrinz2_harness/x86_64/sbin/pci auto
<b>skb_bridge_program=bridge_bios</b></tt><br>
<br>
Also, can you please enable PCI debug output and send the log? For
that, uncomment the following in line 17 of usr/pci/pci_debug.h and
recompile:<br>
<br>
<tt>#define PCI_SERVICE_DEBUG 1 </tt><br>
<br>
Cheers,<br>
Stefan<br>

I re-started my adventure with Barrelfish this morning with the last mercurial
release. I am using tftpboot PXE boot (modified grub etc.). I kept myself from
modify the code at the moment. But I have to confess that I added a PCI_DEBUG()
before this error and nothing was printed even changing the loglevel= . Let me
know if you prefer me to send this error on the forum.

Sounds like a problem Gerd has been dealing with. If that's the case, we
might have a quick-fix for it. Gerd?
cheers,
