From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050224 Firefox/1.0.1 Fedora/1.0.1-1.3.1 Description of problem: Regularly the e100 driver stops functioning. The NETDEV WATCHDOG has to come in and reset the driver/card. It seems to behave correct under Windows 2k. Also does it seems to behave correct when connected to a 100Mbit/Full-duplex line. I'm usally on 10Mbit/Half-duplex. I've had this problem before years ago (+-3 year), but then the problem was solved by using the e100 driver instead of the eepro100. At this moment the eepro100 doesn't work at all and constantly gives wait_for_cmd_done timeout errors. Version-Release number of selected component (if applicable): 2.6.10-1.770_FC3 How reproducible: Always Steps to Reproduce: 1. Boot the machine 2. Do some network related activity 3. Wait a while, sometimes it takes longer than other times before it starts. 4. The card stops functioning and a few seconds later it's resetten by the kernel and it works again. Actual Results: A temporary loss of connection Expected Results: No loss of connection Additional info: Toshiba satellite pro 4600 intel etherexpress 100

I believe that I am experiancing a similar bug. When attempting to play a mythtv recording from a remote machine the e100 driver will crash. The differenct appears to be that the network does not work after the network watchdog brings it back up. The machine is a Toshiba satellite 2805-s402 and the network card is a intel etherexpress 100

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
The problem had somewhat faded to a less-frequent case lately. With this new kernel it seems to have dissapeared. If it comes back, then I will let you know. I'm in the planning of installing FC4, so I'll update this record appropriately then.
Seems I was just a few hours to early. It just droppped out again. Leaving only the following message: kernel: e100: eth0: e100_watchdog: link up, 10Mbps, half-duplex I'm sorry for any inconvinience from my last post.
Maybe bad device? Or trable at "sleep mode". I have same device, but have not problems with it.
Could you post the output from `lsmod` and a complete `dmesg -s`?

Per request I've updated to version fieldto FC4, since I'm running FC4 now and the problem has remained.
I think you may have a similar issue as bug 172067. Everyone affected by this seems to be using toshiba satellite notebooks. Could you try the `echo 3 >/proc/acpi/sleep` and wake to reproduce the bug? I don't necessarily advise people to try the rmmod trick from 172067. I've corrupted my filesystem before by rmmodding network drivers and modprobing new versions.
Tried the echo trick, but ethernet works fine before and after that. I'll try some mouse movement when the card malfunctions. All I got was a nice kernel stacktrace for an illegal context in slab.c.
Mass update to all FC4 bugs: An update has been released (2.6.14-1.1637_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks.
Closed due to lack of response. Please reopen when the requested information becomes available...thanks!
