[ewg] Crash in iw_cxgb3 (Chelsio) in OFED 1.4.1

[pandit ib]

We are seeing a kernel panic in iw_cxgb3 in OFED 1.4.1 (attached screen shot)

The problem seems to be happening at....

ofa_kernel-1.4.1/drivers/infiniband/hw/cxgb3/cxio_hal.c:112


 109                 while (!CQ_VLD_ENTRY(rptr, cq->size_log2, cqe)) {
 110                         udelay(1);
 111                         if (i++ > 1000000) {
 112               -------->        BUG_ON(1);
 113                                 printk(KERN_ERR "%s: stalled rnic\n",
 114                                        rdev_p->dev_name);
 115                                 return -EIO;
 116                         }
 117                 }


Any ideas?
Is it a known issue and if so is there a fix or workaround?


Thanks,
Ranjit
