Samba wedges boot with kernel 2.6.16-1.2107_FC5

Description of problem:
Version-Release number of selected component (if applicable):
4 out of 5 times
Steps to Reproduce:
1. "upgrade" kernel to 2.6.16-1.2107_FC5 on a machine running samba
boot process wedges hard when service smb starts
Since there was no change to my samba configuration , I suspect that this is a
I saw this behaviour 3/3 times with kernel-2.6.16-1.2107_FC5 and 1/2 times with
kernel-smp-2.6.16-1.2107_FC5, both on a hyperthreaded P4. Since NFS was hosed
and I serve several partitions, using both NFS and samba, to my network from
this machine, I gave up at that point.
NB X was not running, so this seems unrelated to the X bugs,
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190575, but is possibly
does booting with pci=nomsi make this go away?
Actually, that option is also broken in this kernel (sigh).
2108, available from http://people.redhat.com/davej/kernels/Fedora/FC5/
has this disabled by default. Give that a try ?
With 2108 I see the same not quite every time failures: 0/1 success with the up
kernel, 1/2 success with the smp kernel.
Once again, even when samba doesn't hang the boot, NFS mount requests to the NFS
server on this machine hang.
For your edification I'm adjoining the dmesg output from the non-samba-hanging
boot and an ethereal packet capture of the hanging NFS mount request.

dmesg output from 1/4 non-samba-hanging boot
Created attachment 128624 [details]
ethereal packet capture of hanging NFS incoming mount request
This is from the 1/4 non-samba-hanging boot with 2108
2111 solved my problem
