Description of problem: On RHEL4 hosts with QLogic FC HBA, any command interacting with "qioctlmod" module hangs after FC target faults. For example, after offline and online of target ports on NetApp controller, the command "scli" hangs. "scli" - SANsurfer CLI is management tool (command line interface) for use with the QLogic Linux driver. How reproducible: Always Version-Release number of selected component: OS - RHEL4 (observed on both RHEL4.7 ad RHEL4.8) Driver - Inbox drivers (8.02.09.02.04.08-d on RHEL4.8) Actual results: Any command interacting with "qioctlmod" module hangs. Expected results: Any command interacting with "qioctlmod" module should not hang.

Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products.

Anyone got a backtrace from this hang? sysrq-t/crash output would be great.
I'm pulling the cluster-4.8.z flag because this is a kernel issue, not a cluster issue. Someone may want to request a rhel-4.8.z flag.
This is a serious usability problem. Setting rhel-4.8.z flag.
