Today's next failed to boot on my 4 way x86_64 box because of mptbase driver initialization failure. Snippet of messages during boot : Fusion MPT SAS Host driver 3.04.14 mptsas 0000:03:04.0: can't find IRQ for PCI INT A; probably buggy MP table mptbase: ioc0: Initiating bringup ioc0: LSISAS1064 A3: Capabilities={Initiator} mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! mptbase: ioc0: Initiating recovery mptbase: ioc0: Attempting Retry Config request type 0x1, page 0x2, action 0 mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! mptbase: ioc0: Initiating recovery mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! mptbase: ioc0: Initiating recovery mptbase: ioc0: Attempting Retry Config request type 0x1, page 0x1, action 0 mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! Eventually machine fails to boot. I have similar problem on a x86 box but with IPS driver. So might not be a driver specific issue. I had similar problem with yesterday's next.IIRC the last successful boot was with next-20100203. Have attached the boot log from x86_64 box.
