[Bug 94940] Re: mdns listed in nsswitch.conf causes excessive time for dns lookups

2008-01-07 Thread ed_p
After reading through related bugs, it looks like avahi / nss is trying multicast dns before traditional dns. With multicast DNS, the only real option is long timeouts and retries, since only one avahi-enabled machine on the network may have a response for a given request. (That is, a successful lo

After some stracing and tcpdumping, it looks like the changed behavior here is that when mdns gets an NXDomain response, it retries up to 5 seconds, then reports a "timeout" to the requesting client, rather than immediately reporting that the record doesn't exist. Is there a reason why requests th

So ndiswrapper works, but that solution only helps x86, and not other supported platforms (ppc, sparc). When possible, it's better to fix a driver than to retreat to ndiswrapper. -- Ralink Wireless USB/PCMCIA/PCI hangs PC https://bugs.launchpad.net/bugs/34902 You received this bug notification be

This seems to be a bug in the rt2570 module. Since you can also use ndiswrapper to drive these cards (at least those of us on intel boxes), there is a simple workaround: disable the rt2570 module. You can compile it out, or just add these two lines to your /etc/modprobe.d/blacklist: # use ndiswrap

Oh, more information, for those more interested in getting their card working than in fixing kernel bugs: I was able to get my card up by properly configuring /etc/network/interfaces manually, in the standard Ubuntu kernels, with DHCP. I can get exactly one "ifup" command through per reboot. You c

Here is some additional information: Playing around in a text console, it appears that the "freeze" is caused by a kernel panic that occurs when we hit a BUG in a bh context at kernel/timer.c, line 411 (in cascade, an inline function that appears in __run_timers, which itself is an inline function
