I've bisected the patch series and the winner is #221 git-scsi-misc.patch which seems to contain eight commits. I think SCSI people can hunt this down from now on. The bug happens whenever sr block device is accessed - mount, cat, whatever, and now it seems like some kind of data overrun. Hope it helped. -- tejun - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
