* do_IRQ stack overflow on 32-bit CentOS 4 @ 2009-06-30 17:00 Orion Poplawski 2009-06-30 17:52 ` Eric Sandeen 0 siblings, 1 reply; 3+ messages in thread From: Orion Poplawski @ 2009-06-30 17:00 UTC (permalink / raw) To: linux-xfs Just hit a: do_IRQ: stack overflow: 452 on 32-bit CentOS 4 machine with xfs-kmod-0.4-2.el4. Is there anything that can be done to minimize this risk? Running xfs over md raid5 array, exporting via nfs. More kernel dump messages are posted at: http://bugs.centos.org/view.php?id=3136 Thanks! _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 3+ messages in thread

See http://lkml.org/lkml/2007/8/29/245 This was fixed in 2.6.18-108.el5 and beyond. Upstream has some xfs stack size fixes; this may eventually make it to a centos near you. -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 3+ messages in thread

Oh, for RHEL^wCENTOS4 it was fixed in 2.6.9-78.8.EL and beyond. -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 3+ messages in thread
