Red Hat Bugzilla – Bug 186708
FC5 kernel lockups, call trace, network hangups
Last modified: 2008-08-02 19:40:33 EDT
Description of problem:
I having massive problems with the default FC5 i686 kernel. I tried to install
FC5 using a PXE network install. The network card is detected (tg3 driver) the
systems gets an IP address via DHCP. After entering the NFS server name and path
to the DVD image my whole network is being blocked after some time, i.e. no
other system can communicate with the NFS server anymore. The NFS server is
RHES4U3. After switching off the FC5 install client the network becomes usable agin.
As network install is impossible I decided to install FC5 locally from the DVD.
When I booted the system after the install process I saw a call trace (see
screenshot #1) the boot process continued but then hung completely (see
After rebooting the system came up completely but my network was blocked again
after some network activity.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. have some network activity on a tg3 network card

Problem still persists with kernel-2.6.16-1.2080_FC5.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.
Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.
In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
Still the same problems here with the current FC6 kernel. In the meantime I
found out that my system is stable when I pass "noapic acpi=off" to the kernel
(this is a mass-close to kernel bugs in NEEDINFO state)
As indicated previously there has been no update on the progress of this bug
therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue
still occurs for you and I will try to assist in its resolution. Thank you for
taking the time to report the initial bug.
If you believe that this bug was closed in error, please feel free to reopen
