linux-scsi, target-devel,
We're noticing consistent kernel lock-up issues with RH 3.10 kernels, esp.
while dm targets are under concurrent load from iscsi and local disk
access. Issue is reproducible with load on disks over time. Sample call
trace below; what additional information can I help to provide on this?
