My assumption this is the same libnl issue that we recently fixed in RHEL 5.2.
I will investigate but for now moving to libnl.
Adding dcbw and tgraf to the CC list.
This is identical to what we recently fixed in RHEL5.2 (BZ 434826). Do we want
to fix this in the same way? I know there were other ideas on how to better fix
this however we didn't want to break binary compatibility on RHEL5.X. Perhaps
we want to implement that fix in Fedora.
The way it was fixed in RHEL5.2 is also the way I fixed this upstream. There is
really is no other way unless the kernel enters an unstable cycle again allowing
for the netlink protocols to break.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
Closing since we are not currently building Fedora on ia64. Will re-open if this is still seen once builds begin again.
