Doesn't look like a regression to me. Doubled timeout looks like a problem with timer. I'll follow up on the original thread.

Not really a regression. Alan seems to have a general fix and I think we can also quirk the specific case.

Status : Unknown

I was traveling abroad last week, without access to my devel environment. Hans is currently working on a definitive fix for the issue. His schedule is to have a proper solution until next week.

For now, it is better just to revert the bad changes. I've committed a patch on my tree for that:

http://git.kernel.org/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=15ac2d293b08b6975c6ca1a80eb839d4cb0dddbf

I'm currently running some tests on my environment with the fix patches I currently have. I should send a pull request to Linus later today.

Looks more like the IPV6 SNMP6 OOPS, I saw and fixed with:

commit 5632c5152aa621885d87ea0b8fdd5a6bb9f69c6f

Author: Stephen Hemminger <[email protected]>
Date:   Sat Apr 28 21:16:39 2007 -0700

[IPV6]: Track device renames in snmp6.

When network device's are renamed, the IPV6 snmp6 code gets confused. It doesn't track name changes so it will OOPS when network device's are removed.

The fix is trivial, just unregister/re-register in notify handler.

It's quite possible that this fixes it, especially since the version in Ubuntu's bug report came out the day before your fix went in :)

However, I don't really get why it's crashing in the first place. Without your patch, if the device is renamed the proc entry just keeps the original name. When it goes down it should still get removed correctly.

Could you explain this in a bit more detail?

Thanks,
