the output of dmesg
diff -u dmesg-good dmesg-bad Interrupts in kernel 2.6.23 lspci output in 2.6.23 lspci output in 2.6.26.5 network interfaces Patch to print a warning if the MAC address is all 0s |

Please attach the output of "dmesg" after booting the problem kernel I think for version 2.6.26.5 and others is the same output of "dmesg".

I'm sorry, but gmail said that I can't send I emails for you, because "it was rejected by the recipient domain". Beats me but I don't have any idea too. The fack is, I didn't change any configuration in system and I compiled every kernel with the same configuration but it isn't working. I'm sorry, but I don't understand it, so I wrote to you. Please, ask me for everything you want. I'm absolutly waiting on yours hand and foot. Andrew Morton wrote, On 10/04/2008 12:33 PM:

I guess it's because of this missing MAC address (as seen in your dmesg):
eth0: SiS 900 PCI Fast Ethernet at 0xd400, IRQ 10, 00:00:00:00:00:00
Jarek P.
PS: there was a change of kernel policy wrt. this.
I have the same issue. And its ifconfig eth0 hw ether 01:23:45:67:89:ab that causes SIOCSIFHWADDR: cannot assign requested address I tried all kind ow hw-addresses to no avail. Is this regression still present in the latest kernels ? Created attachment 19560 [details] Patch to print a warning if the MAC address is all 0s I have added a simple patch to bug 10201 that prints a warning if the MAC address read from the hardware is composed of all zeros. It needs a runtime test, then should be included. I'm also attaching it here for convenience. Please submit patches via email. Add a signed-off-by and a nice changelog. Please cc this one to netdev@vger.kernel.org and akpm@linux-foundation.org, thanks. Is this regression still present in the latest kernels ? Also, was the patch mentioned by Daniele ever posted via email? I forgot about this the instant I submitted the comment above. I have no recent information on this, I'm sending the email right now. Patch got in January 2009, with commit d1d5e6b1cead3df6f722d1d458874bd7f93da8d6. |
Latest working kernel version: 2.6.23.x Earliest failing kernel version: 2.6.24.x Distribution: Debian Etch 4.0 Hardware Environment: PC Software Enviroment: Problem Description: I installed Debian Etch 4.0 (with kernel 2.6.18-6-k7) on my machine with ECS K7S5A with built-in network card SIS900. During the installation and after first boot internet worked like a dream with auto configurated DHCP interface. But after change kernel to version 2.6.26.5 internet didn't work. In this moment I realized that I didn't change internet configurations, but I thought that it can be wrong in hardware configurations. On the other hand, the results by lspci and lspci -n, said that everything had worked perfectly. Then, I compiled kernel 2.6.26.5 with exacly the same .config file like kernel from debian distribution (2.6.18-6-k7) and internet didn't work too. After that, I compiled older kernel (2.6.17) with this .config file and internet started working! I think, it is proof that it is something wrong in module sis900 in the newest kernel versions, because I didn't change others system configurations! What is more, system didn't have interrupt for ethernet, thought lspci recognized network card, sis900 module was started and DHCP was set. To confirm my view I attache interrupt's list and logs from internet starting/restarting: tanya:/home/daimyo# cat /proc/interrupts CPU0 0: 430048 XT-PIC-XT timer 1: 185 XT-PIC-XT i8042 2: 0 XT-PIC-XT cascade 3: 1 XT-PIC-XT 4: 1 XT-PIC-XT 5: 0 XT-PIC-XT ohci_hcd:usb2 6: 5 XT-PIC-XT floppy 7: 0 XT-PIC-XT parport0 8: 1 XT-PIC-XT rtc 9: 1 XT-PIC-XT acpi 10: 2 XT-PIC-XT ehci_hcd:usb5, SiS SI7012 11: 228 XT-PIC-XT uhci_hcd:usb3, uhci_hcd:usb4 12: 0 XT-PIC-XT ohci_hcd:usb1 14: 42772 XT-PIC-XT ide0 15: 30385 XT-PIC-XT ide1 NMI: 0 Non-maskable interrupts LOC: 0 Local timer interrupts RES: 0 Rescheduling interrupts CAL: 0 function call interrupts TLB: 0 TLB shootdowns TRM: 0 Thermal event interrupts SPU: 0 Spurious interrupts ERR: 0 MIS: 0 tanya:/home/daimyo# sudo /etc/init.d/networking restart Reconfiguring network interfaces...There is already a pid file /var/run/dhclient.eth0.pid with pid 7018 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.0.4 Copyright 2004-2006 Internet Systems Consortium.
