Description : linux-2.6.32-s390-qdio_input_error.patch Description: qdio: reset error states immediately Symptom: Connection stall on OSA cards. Problem: The qdio hardware may surpress further interrupts as long as a SBAL is in the error state. That can lead to unnotified data in the SBALs following the error state. Solution: Change the SBAL[s] in error state immediately to another program owned state so interrupts are again received for further traffic on the device.

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? http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=bffbbd2df4196a73ffdc16709866dd96eb66aad8 What is the latest official Red Hat build on which this bug has been seen? RHEL6.1 The patch has been tested, fixes the problem, and is part of the upstream kernel. With best regards, Hendrik
