Description of Problem: Kernel panics. Panics occur at different places, most typically when loading SCSI drivers and/or performing I/O. ITP indicates 3 processors at last bundle in stop_this_cpu()routine , 4th proc in last bundle of panic() routine. The hangs also often occur during boot. System log indicates BUG() at slab.c:1746. Further, I have tried many combinations of adapters, including only using the qla12160 (boot device) and have still observed the failure. Failure is consistent. Failures have been observed on 4-way Itanium systems with latest BIOS (105B) and firmware. Version-Release number of selected component (if applicable): Rh 7.2 with 2.4.9-18smp kernel. Adapters used in configuration: - Mylex eXtremeRAID 2000 - Adaptec 39160 - Qlogic 12160 - AMI 1600 MegaRAID - Pro 100 NIC - Pro 1000 NIC - Qlogic 2200/66 FC All drivers used were drivers included in the Redhat distribution kernel tree. How Reproducible: Always. Steps to Reproduce: 1. Boot system 2. Load driver(s) for adapters 3. panic/hang... Actual Results: System hangs(panics). Expected Results: System to run... Additional Information:
Would it be possible to drop one driver at a time to find the culprit? The order of suspects would be: 1) DAC960 2) qla2200 3) qla1280 4) megaraid 5) e1000 6) eepro100
