Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I have a 486 box which ran 2.5.7 fine, but 2.5.8 oopses during boot at the BUG_ON() in drivers/ide/ide-disk.c, line 360: if (drive->using_tcq) { int tag = ide_get_tag(drive); BUG_ON(drive->tcq->active_tag != -1); Relevant .config is # CONFIG_PCI is not set CONFIG_IDE=y CONFIG_BLK_DEV_IDE=y CONFIG_BLK_DEV_IDEDISK=y CONFIG_IDEDISK_MULTI_MODE=y (That's it. No chipset support selected; neither I nor Linux has ever detected any known IDE chipset in this box...) Why is drive->using_tcq non-zero when CONFIG_BLK_DEV_IDE_TCQ=n and the disk is an early/mid-90s 500MB WD drive? /Mikael - 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/
