From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-2 Firefox/1.0.3 Description of problem: After upgrading to FC4T2 my network card stopped working. I have tried the following kernels, not function correctly: kernel-2.6.11-1.1226_FC4 kernel-2.6.11-1.1258_FC4 kernel-2.6.11-1.1261_FC4 The following is the lspci line relevant: 02:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 20) The 8139cp loads correctly, but limited traffic gets through. I rarely get DHCP leases, if I staticly set the IP I get a package through now and then, every other minute or so. What I see in the messages log is the following: Apr 27 14:33:44 uber kernel: NETDEV WATCHDOG: eth0: transmit timed out Apr 27 14:33:44 uber kernel: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 Apr 27 14:33:56 uber kernel: NETDEV WATCHDOG: eth0: transmit timed out Apr 27 14:33:56 uber kernel: eth0: link up, 100Mbps, full-duplex, 1pa 0x45E1 ... If I boot the machine in rescue mode with a Fedora Core 3 CD I can activate the network and it works.

Tried the latest kernel update and the problem still exists. 2.6.11-1.1275_FC4.
Does this device work w/ the 8139too driver? # ifdown eth0 # modprobe -r 8139cp # vi /etc/modprobe.conf # change 8139cp to 8139too # ifup eth0
I've actually tried that also. Same result.
This sounds somewhat similar to the symptoms I'm experiencing with my b44 Ethernet card: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=154512
Finally found out what was causing the problem, and hopefully you guys can fix it, all I have is a workaround... I found out that if I booted linux with "init=/bin/bash" and started networking, it worked. So I hacked for a while through rc.sysinit until I found that when tpm_atmel was loaded, 8139cp stopped working. My workaround was adding "tpm_atmel" to /etc/hotplug/blacklist, hope this helps.
More problems emerge. Now tpm_nsc loads on boot with the same negative effect on my network adapter. Now I have both tpm_atmel and tpm_nsc in /etc/hotplub/blacklist.
There has been some recent activity with the tpm driver. I've included those patches in the kernels here: http://people.redhat.com/linville/kernels/fc4/ Please give them a try and post the results. Go ahead and remove the tpm-related modules from /etc/hotplug/blacklist before testing. Thanks!
Same result with your kernel 2.6.11-1.1288.2.1_FC4.jwltest.1. Have not tested the most recent ones.
Please try ...jwltest.3 (or later) from the same location as in comment 7. I have been in contact w/ the tpm driver maintainer, and those kernels include some changes suggested by her. Please post the results of testing those kernels. Thanks!
*** Bug 158291 has been marked as a duplicate of this bug. ***
Created attachment 114829 [details] jwltest-tpm-fixes.patch This patch appears to fix the problem for (at least some) users...
tpm drivers do not load anymore by default so this has been worked out some other way. I will try the jwltest kernel later today.
The tpm drivers aren't currently being built. However, we'd like to be able to include them if we can fix them so that they don't cause problems for you. I appreciate your help!
2.6.11-1.1363.2.1_FC4.jwltest.5 confirmed working. I transfered a few gigabytes via NFS without a problem. # lsmod | grep tpm tpm_atmel 5569 0 tpm 12385 1 tpm_atmel
I'm going to close this for now...either tpm will remain disabled, or it will get re-enabled along w/ this patch (or an equivalent update from upstream)... Thanks for the testing!
