Hi, I recently decided to update my alpha UP1000 to today's current from a mid-July build. However, UDMA33 did not work on a hard disk attached to the built-in Acer Aladdin controller (verbose dmesg appended). I think I have narrowed the problem down to this line of code: atadev->channel->flags |= ATA_ATAPI_DMA_RO; Removing this line gets my UDMA33 back. Cheers, Drew Patch to hack around problem: Index: ata-chipset.c =================================================================== RCS file: /home/ncvs/src/sys/dev/ata/ata-chipset.c,v retrieving revision 1.39 diff -u -r1.39 ata-chipset.c --- ata-chipset.c 8 Sep 2003 13:55:05 -0000 1.39 +++ ata-chipset.c 8 Oct 2003 19:43:30 -0000 _at__at_ -382,7 +382,10 _at__at_ if (ctlr->chip->cfg2 & ALIOLD) { /* doesn't support ATAPI DMA on write */ +#if 0 + /* XXX this breaks ATA disk DMA support */ atadev->channel->flags |= ATA_ATAPI_DMA_RO; +#endif if (atadev->channel->devices & ATA_ATAPI_MASTER && atadev->channel->devices & ATA_ATAPI_SLAVE) { /* doesn't support ATAPI DMA on two ATAPI devices */ Dmesg from failure: Copyright (c) 1992-2003 The FreeBSD Project.
