Bug#590327: linux-image-2.6.32-5-amd64: Unbalanced enable for IRQ 19
Package: linux-2.6
Version: 2.6.32-18 Severity: minor I'm getting this warning for quite a while now, but not on every boot. Stack traces below ide_pci_init_two differ slightly. I've also tried the current experimental kernel, but the warning is still there (although the stack trace is somewhat different). -- Package-specific info: ** Version: Linux version 2.6.32-5-amd64

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>.

However, the IDE core attempts to disable and enable the IRQ *before* it allocates it. If the UHCI driver then allocates the IRQ in the middle of this, the IRQ manager will reset the disable count since the IRQ is not yet shared! This might be fixable by changing the IDE core to allocate the IRQ with a dummy interrupt handler while probing. Aside from that, maybe pata_it8213 is ready as a replacement for it8213 now?

(Kconfig still labels it as EXPERIMENTAL.) I've known about this IDE layer problem for at least a year and any fix is too risky to consider seriously. Use the PATA drivers on modern systems, don't use the deprecated IDE layer. -- To UNSUBSCRIBE, email to debian-kernel-REQUEST@lists.debian.org with a subject of "unsubscribe". Trouble?

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.) Ben. |

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-REQUEST@lists.debian.org with a subject of "unsubscribe". Trouble?
