Description Jeff Burke 2008-03-17 14:16:35 UTC
Description of problem:
 After upgrading from RHEL5.1 to RHEL5.2-Client-20080313.0 the system has a 90
second pause while booting. This happens when the service network is starting.

04:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5754 Gigabit
Ethernet PCI Express (rev 02)

Version-Release number of selected component (if applicable):
 2.6.18-85.el5

How reproducible:
 Always

Actual results:
 While booting the system appears to hang. Waiting for 1.5 min the system will
then continue. I then see a bunch of new messages about netplug.d

Driver ifd-egate.bundle does not support IFD_GENERATE_HOTPLUG. Using active

Expected results:
 System should boot without long delays.

Comment 1 Andy Gospodarek 2008-03-17 19:06:06 UTC
Are you pretty sure this card is causing the problem?  Is this a system in rhts
or your laptop or something?

The tg3 driver hasn't been touched since 2.6.18-62.el5, so this would be
surprising if it was a tg3 problem.



Comment 2 Jeff Burke 2008-03-17 19:59:35 UTC
Andy, 
  Just going by the bootup screen No I am not 100% positive but as the system
boots. I see the following:
Checking for Hardware Changes     [OK]
Bringing up looback interface     [OK]
Bringing up eth0 interface   <-Pause for long time  [OK]


Comment 3 Jeff Burke 2008-03-17 20:00:01 UTC
Andy,
    Also this is my desktop system.

Jeff

Comment 4 Andy Gospodarek 2008-03-17 20:21:23 UTC
Jeff what model workstation is it?  If it's an HP I can probably get my hands on it.

Comment 5 Jeff Burke 2008-03-17 20:30:57 UTC
It is a Dell Precision 390

Comment 6 Andy Gospodarek 2008-03-17 21:04:37 UTC
based on comment #2, seems pretty likely the tg3 card is the problem. :)

Does it do this if you stop and start the network as well?  If so could you try
and capture the traffic wireshark so I can see what is happening?


Comment 7 Jeff Burke 2008-03-18 15:12:52 UTC
Andy, 
  It does have the same issue when doing a service network restart. I need to
get some additional work down so I am not sure when I will be able to try and
get a packet capture

Comment 8 Andy Gospodarek 2008-03-18 18:31:53 UTC
No problem, Jeff.  I'll see if I can track down a system with a 5754 in the
meantime.

Comment 9 Andy Gospodarek 2008-10-07 18:10:07 UTC
Jeff, is this still an issue?

Comment 10 Jeff Burke 2008-10-07 18:21:26 UTC
Andy,
    I will have to double check. It is my desktop system that I was seeing the issue on. I don't reboot that often So I am not 100% sure at the moment. I will get back to you in a day or so.

Thanks,
Jeff

Comment 11 Jeff Burke 2008-10-07 20:43:53 UTC
Andy,
    I was able update my ststem to the latest R5.2-Z stream kernel  2.6.18-92.1.13.el5. I no longer see the issue. During the init scripts it seems to be "normal" again. I don't see any long pauses.

    I think we can close this as NOTABUG or WORKSFORME.

Thanks,
Jeff

Thanks, Jeff!
