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
