Description of problem: When I soft-reboot my RHEL 5.5 host, the mac addresses change, the first 4 Bytes of the 6 Bytes MAC becomes zeroes. Version-Release number of selected component (if applicable): Kernel 2.6.18-194.el5 How reproducible: At each soft reboot (on demand) Steps to Reproduce: 1. Cold boot the machine, note the MAC address 2. Soft reboot the machine, note the new MAC address 3. Actual results: 00:00:00:00:2e:01 Expected results: 00:0a:cd:19:2e:01 Additional info: 02:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10) It is the exact same bug as reported for fedora 12 about a month ago, see https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=573201
This issue should be fixed by this upstream commit: 78f1cd0 - r8169: fix broken register writes [http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=78f1cd02457252e1ffbc6caa44a17424a45286b8] I'm going to prepare test packages.
There are kernel packages for testing at http://people.redhat.com/ivecera/rhel-5-ivtest/. Could you please try them?
I confirm that this kernel fix my problem. The machine successfully soft rebooted and kept the right MAC address. # uptime 16:30:58 up 1:01, 1 user, load average: 0.00, 0.00, 0.00 # uname -a Linux xxxx.polymtl.ca 2.6.18-197.el5.ivtest.1 #1 SMP Tue Apr 27 07:09:22 EDT 2010 i686 i686 i386 GNU/Linux # ifconfig eth0 | fgrep HWaddr eth0 Link encap:Ethernet HWaddr 00:0A:CD:19:2E:01 Xtian.
