Description of problem: Version-Release number of selected component (if applicable): 2.6.16-1.2107_FC5 How reproducible: 4 out of 5 times Steps to Reproduce: 1. "upgrade" kernel to 2.6.16-1.2107_FC5 on a machine running samba 2. reboot 3. Actual results: boot process wedges hard when service smb starts Expected results: boot completes Additional info: Since there was no change to my samba configuration , I suspect that this is a kernel issue. 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=190424 or https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190575, but is possibly related to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190543.
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.
Created attachment 128623 [details] 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
