Description David Somayajulu 2006-11-14 18:24:15 EST
Description of problem:
Each port on qla4xxx has two MACs, one is used for Ethernet Network Interface 
(supported by qla3xxx) and the other used of iSCSI. The above interfaces are 
supported as a single chip solution. The problem happens when both qla3xxx and 
qla4xxx drivers are loaded. The issue happens when the iSCSI Interface issues 
a reset in response to a Network Reset without first grabbing the Qla4xxx 
Hardware semaphore.

Version-Release number of selected component (if applicable):

How reproducible:
Load the qla3xxx driver with qla4xxx already loaded.

Steps to Reproduce:
Actual results:
Networking halts.

Expected results:
Both network and iSCSI interfaces should exist happily.

Additional info:
In addition the enclosed patch gets rid of support for a version of qla4xxx 
called TOPCAT which never shipped and will never ship.

Yes, the patch in RHBZ 215641 appears to correct this issue.  The patch
applied to the -2747 kernel and has been tested on JS20 and POWER5.

Thanks Konrad.
Comment 8 Jay Turner 2006-12-04 20:16:29 EST
QE ack for RHEL5.  Setting blocker, otherwise the issue won't get picked up for
RHEL5.  This is a bug in new hardware support.
Comment 9 Konrad Rzeszutek 2006-12-14 13:07:02 EST

Has this patch been posted for inclusion in RHEL5?
Comment 12 Konrad Rzeszutek 2006-12-19 10:48:02 EST

Any outlook with having this BZ? Is the patch for this problem already posted on

I am looking in the RHKL for this patch and I cannot find it? Can you provide
the URL or the date when you posted this patch?

Konrad, do you still need a link or something? All the patches that were listed
in the 4032 support bugzilla
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=213807 in comment #20 were
rolled up into a one large patch and merged last week.
Comment 18 Tom Coughlan 2007-01-11 10:20:01 EST
Comment 17 says this went in as part of the 213807 fix. That BZ is MODIFIED, so
I am setting this likewise. 
Comment 19 RHEL Product and Program Management 2007-02-07 19:28:38 EST
