Pinned topic An issue with SLES 11 SP2 (linux 3.0 kernel) requires a fix

Unanswered question This question has not been answered yet.
When GPFS is used on SLES 11 SP2 (Linux 3.0 kernel), under certain workloads (in particular when NFS export of GPFS file systems is involved) a deadlock in kernel code may occur. The problem is currently under investigation. Customers are advised NOT to upgrade to SLES 11 SP2 until a fix is available. This announce forum and the GPFS FAQ (http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=/com.ibm.cluster.gpfs.doc/gpfs_faqs/gpfs_faqs.html) will be updated when the fix is available.
