Description Joe Christy 2006-05-03 20:15:03 UTC
Description of problem:

Version-Release number of selected component (if applicable):

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
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

does booting with pci=nomsi make this go away?

Comment 2 Dave Jones 2006-05-04 04:14:40 UTC
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 ?

Comment 3 Joe Christy 2006-05-04 19:21:17 UTC
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 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
