Description Joseph Kachuck 2011-02-21 16:32:12 UTC 
linux-2.6.18-s390-qeth-no-ipa-in-offline.patch

Description: qeth: remove needless IPA-commands in offline
Symptom: slow or even hanging shutdown of qeth devices
Problem: If a qeth device is set offline, data and control
subchannels are cleared, which means removal of all
IP Assist Primitive settings implicitly. There is
no need to delete those settings explicitly.
Moreover shutdown of qeth devices may even hang
if hardware currently has a problem to handle those
IPA-commands.
Solution: This patch removes all IP Assist invocations from
offline.

Server architecture(s): System z
Server type: s390x
General component: kernel
Other components involved: No

Does the server have the latest GA firmware?
Yes.

Has the problem been shown to occur on more than one system?
Yes.

Is a tested patch available?
Yes.

If yes to the above, has it been approved upstream?
The patch has been recently sent upstream.

What is the latest official Red Hat build on which this bug has been seen?
RHEL 5.6


The patch has been tested and fixes the problem.

With best regards,
Hendrik
