Don't enable reporting on bank 0. IIRC BIOS initialises that bank and then shouldn't be touched (it's written somewhere in the IA32 manuals). I checked AMD documentation for MCE and it seems that bank 0 doesn't need any special treatment. > Restarting tasks... done > ACPI Error (evevent-0312): No installed handler for fixed event [00000002] > [20060127] > hda: dma_timer_expiry: dma status == 0x21 > hda: DMA timeout error > > This ACPI thing is new.

Yes, it's button.ko that is missing. > It's interesting here that it's complaining about ide dma > timeout, since I disabled DMA before suspend. I'm not sure that the setting is preserved. Anyway the bus is locked and it seems that it's caused by IDE. I saw patches on lkml that added support for running ACPI methods to bring IDE back to life. But it seems that it's only for libata: http://marc.theaimsgroup.com/?l=linux-ide&m=114064719815111&w=2 I can't find the patch neither in mainline nor in -mm. Pavel? Rafael? If you're brave enough you can use libata-PATA patch (Alan Cox) and Randy's patch... ;) Luca Using Tomcat but need to do more? Need to support web services, security?
