Bug#590327: linux-image-2.6.32-5-amd64: Unbalanced enable for IRQ 19
Jan Echternach reported that on his system it8213 provokes the warning Unbalanced enable for IRQ 19 when probed at boot time. The previous messages are logged at http://bugs.debian.org/590327.

Use the PATA drivers on modern systems, don't use the deprecated IDE layer. Well, I'm concerned with what to do in distro configurations which aren't just for 'modern systems'. We already swapped over all the drivers not labelled as experimental. With the rest, I worry that we'd be exchanging obscure IDE drivers that mostly work for obscure libata drivers that have had little if any testing. That strikes me as being even more risky for the users with the old controllers. I suppose that for those controllers where the libata driver is experimental we could build both drivers, blacklist the IDE drivers and let people override that if necessary. (And hope that most of the bugs get shaken out of the libata drivers before we do a stable release, because that is too ugly to keep doing for long.)

But for the cases these bugs are hitting these are systems the old drivers never could have worked on, because of the IRQ sharing issue with things like USB controllers. I think your blacklisting idea probably makes the most sense. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
