The "Badness in iosapic_unregister_intr at arch/ia64/kernel/iosapic.c:851" messages are caused by a missing call to free_irq() in the mpt/fusion driver. I think that it should go here ... but someone with a clue should verify: diff --git a/drivers/message/fusion/mptbase.c b/drivers/message/fusion/mptbase.c --- a/drivers/message/fusion/mptbase.c +++ b/drivers/message/fusion/mptbase.c @@ -1384,6 +1384,8 @@ mpt_suspend(struct pci_dev *pdev, pm_mes /* Clear any lingering interrupt */ CHIPREG_WRITE32(&ioc->chip->IntStatus, 0); + free_irq(ioc->pci_irq, ioc); + pci_disable_device(pdev); pci_set_power_state(pdev, device_state); But even this doesn't fix the hang during shutdown :-( The remaining problem is cause by the order of the calls in sys_reboot: device_suspend(PMSG_SUSPEND); device_shutdown(); The call to device_suspend() shuts down the mpt/fusion driver. But then device_shutdown() calls sd_shutdown() which prints: Synchronizing SCSI cache for disk sdb and then calls sd_sync_cache(). Now since we suspended mpt/fusion, this is going to go nowhere. I don't know how to fix this. Re-ordering the suspend & shutdown just looks wrong. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
