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)
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.
Steps to Reproduce:
1. Boot system
2. Load driver(s) for adapters
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:
