Ok but there are actually 2 real problems then... 1. TCQ on hda is enabled with queue depth 32 and CONFIG_BLK_DEV_IDE_TCQ_FULL enabled When I do many transfers on the hard disk I get a "ide_dma_queued_start: abort (stat=d0)" after some time and the IDE system doesn't respond anymore :( 2. when I cat /proc/ide/ide1/hdc/identify I get 2 unexpected interrupts hdc and hdd are both cdrom drives (accessed via scsi-emulation if relevant) but the problem shows up only with hdc and maybe a third problem ;) in /proc/ide/ide0/hda/tcq there is written: DMA status: not running but DMA is explicitly enabled by hdparm and shows up in /proc/ide/ide0/hda/settings I'll do some more testings later the day Bye --=.TsqYka/1nnHVG6 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) iD8DBQE8vVx3e9FFpVVDScsRAnZGAJ9JA4sUP1AU3Xm2bnxQdiUllIt/UQCgpD51 AqW3Glk0/dvug++9MCv/A7s= =5px5 -----END PGP SIGNATURE----- --=.TsqYka/1nnHVG6-- - 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/
