From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.1-0.1.9 i686; Nav) If I bring up several cipe interfaces and later bring some of them down and back up (several times even, for example, as I tweak ip-up and ip-down scripts), an interface will eventually refuse to load--complaining of 'opendev: alloc: Device or resource busy' or similar. The only way I can get rid of this error is to ifconfig down all my cipe interfaces, remove the module, reinsert the module, and bring up the interfaces again. This is not really acceptable as it may be indicative of more serious problems. Further anecdotal evidence: [01:02:08] <jeremy> draco: yes, cipe likes to have its module removed and reinserted between interface down/up :( Reproducible: Didn't try (having my network be connected somewhat sanely is more important, and I figured I'd file the bug now so you're aware of it) Steps to Reproduce: 1. Set up several cipe interfaces between several computers 2. Bring various interfaces up and down, in various combonations (from a single machine) 3. Also try setting up a single interface and bringing it up and down repeatedly Actual Results: ifconfig shows the interface did not come up, though it should have. The module has to be reloaded to get the expected behavior (just working)
This should be fixed in the current rahwide kernel.
