Red Hat Bugzilla – Bug 189852
Network devices interrupts getting lost
Last modified: 2015-01-04 17:26:43 EST
Description of problem:
I have a Toshiba Satellite A105-1013 laptop with a Realtek 8193 (8193too.ko) and
a built-in Atheros AR5212 wifi (madwifi) and am having trouble with both of
them. Randomly the network devices stop receiving data from the network. I can
see the packets sent from the laptop, but it never seems to recieve any new
packets. The interrupt count in /proc/interrupts never increases for the IRQ
assigned to the network card. Nothing short of a reboot allows the card to work
again. Adding irqpoll to the kernel command line prevents the lockups, but makes
the entire system painfully slow and causes a large number of other problems.
Other kernel options such as noapic, or apic=routeirq cause the system to panic
as soon as the kernel starts to boot.
Version-Release number of selected component (if applicable):
All FC5 released i686 uiniprocessor kernels
Use the network (easy to force by transferring a large video file)
Steps to Reproduce:
1. Bring up network interface (any)
2. Transfer data
Network activity stops, counts in /proc/interrupt stop changing
Network activity continues
I've tried all the released FC5 kernels with the same results. The lockup can
happen after just a few seconds, or after a few minutes. I can't go 15 minutes
without reboot without irqpoll.
Booting into single user and bringing up the network with no other drivers
(USB/sound/cpuspeed/acpi) still has the same problem.

Output of lspci -v

Output of lsmod (running with irqpoll)
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.
This bug has been mass-closed along with all other bugs that
have been in NEEDINFO state for several months.
Due to the large volume of inactive bugs in bugzilla, this
is the only method we have of cleaning out stale bug reports
