Description Matthew Tolentino 2002-01-18 14:56:01 EST
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 

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:

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...

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
