Description Flags
dmesg output shoing irq problem - failed to reserver IRQ none

Description Jason Cole 2006-07-06 19:04:56 UTC 
Description of problem:
I have a dual boot machine.  Under windows, I can see all of my ports of Fibre
Channel connections.  Under RHEL4u2&3, I cannot see all the ports - one or more
ports do not show up.  In the dmesg output, I get an error relating to irqs, but
I don't think this is a system problem, or I would not see all the ports in
Windows, correct?

System Details
Tyan s2892 Motherboard with AMD Opteron 244 chip
nVidia SATA RAID attached internal hdd
(1) QLA2460 PCIx FC HBA
(1) QLE2460 PCIe FC HBA
(1) QLA2342 dual port PCIx FC HBA

I have attached the dmesg output, if that may help.

Version-Release number of selected component (if applicable):
RHEL4 AS u3 and u4

How reproducible:
Every time.

Steps to Reproduce:
1. Put more than 3 ports of FC in the system and boot up.
2. Look in /proc/scsi/qla2xxx/# and you will not see an entry for the number of
ports in the system.
3.
  
Actual results:


Expected results:

This looks like a kernel bug though, so reassigning to proper component.

Read ya, Phil
