Bug#587666: Hangs when loading vlan interface immediately after main interface

In that case doing 'rmmod tg3;modprobe tg3;ifdown eth0;ifdown eth0.3' before ifup will cause it to panic). It's obviously a kernel bug. I can't help you with that. I have to reassign it. The probable cause is the managing of up/down callbacks that vlan cannot handle and has NULL pointers assigned and that tg3 without checking calls. I can advise you to try to build your own kernel. 2.6.33 series is pretty stable *IFF* you leave out bridging vlans on bonds on bnx2 :-). (Those work again in 2.6.34 though with bonds being the culprit). The machine is a HS20 (Type 8832) blade in an IBM bladecenter and unfortunately I've not had any success with Serial Over Lan so I can't currently get a backtrace. I will try to see if I can adjust the resolution sufficiently to take a screenshot of the whole backtrace though. ipmisol? It's pretty easy to set up. But your motherboard must be new enough. The linux based BMC's can handle ipmisol pretty well, but the older non linux based BMC really s...k at doing their job.

Bug#587666: Hangs when loading vlan interface immediately after main interface

I haven't been able to get more information on the actual crash but I've attached a screenshot, just in case its of any use. Could this bug be related to 585770? That bug report uses the same kernel and the tg3 driver also. It's definitely the same bug. I will try changing kernel version to see if that resolves it. Well, compiling a vanilla kernel will not have the: bugfix/all/vlan-macvlan-propagate-transmission-state-to-upper-layer.patch in it, which introduced the bug. They probably left out the parts where the propagate have to check for NULL pointers to see if the propagation is supported ;-). Hmmm, I actually reported/fixed the same type of bug in 2.6.29: vlan-macvlan-fix-null-pointer-dereferences-in-ethtool-handlers.patch But then again a rewrite took place after that to make a better grouping of those functions which makes layering of those devices elegantly,fast and possible. Actually the rewrite is stable/finished around 2.6.34 ;-). If you don't need bonding I would check out 2.6.33.5 ;-). -- .signature not found -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

-- Sorry, I just replied direct instead of to the bug report: loopback is only for the loopback interface. I guess you don't want to have l3 addresses on eth0. Please try: iface eth0 inet static Sorry, I meant manual instead of static. up ip l s eth0 up down ip l s eth0 down Thanks, but it does the same thing. I will look at it more in the morning. I didn't think about the loopback statement as a possible cause. I'm also looking into kexec as a possible way to get some debug information but its an uphill struggle!
