Agreed. -CURRENT is all about development. New ideas will be tried, sometimes (sometimes a lot :) things are going to be broke. I switched to the new ATA driver on Monday. Seems to work but I have some questions. Could someone (sos?) post a quick primer on how to read the probe messages? With the old wd driver I understood the messages and it was readily apparent when something wasn't using DMA, large blocks, etc... The new ATA driver is here to stay. Yep. It needs some serious testing. Yep. If someone would post a quick how-to of stuff to do/look-for I'm sure more people would be willing to test with a smile on their face. Here's the relevant portion of my probe: ata-pci0: <Unknown PCI ATA controller (generic mode)> irq 0 at device 1.1 on pci0 ata-pci0: Busmastering DMA supported ata0 at 0x01f0 irq 14 on ata-pci0 ata1 at 0x0170 irq 15 on ata-pci0 . . ad0: <Maxtor 71626 AP/QA3C1D20> ATA-? disk at ata0 as master ad0: 1554MB (3183264 sectors), 3158 cyls, 16 heads, 63 S/T, 512 B/S ad0: 16 secs/int, 1 depth queue, PIO ad1: <QUANTUM BIGFOOT_CY4320A/A03.0500> ATA-? disk at ata0 as slave ad1: 4134MB (8467200 sectors), 8960 cyls, 15 heads, 63 S/T, 512 B/S ad1: 16 secs/int, 1 depth queue, PIO acd0: <FX600S/P01> CDROM drive at ata1 as master acd0: read 1033KB/s (1033KB/s), 256KB buffer, PIO acd0: supported read types: acd0: Audio: play, 255 volume levels acd0: Mechanism: ejectable tray acd0: Medium: CD-ROM 120mm data disc loaded, unlocked ata_command: timeout waiting for interrupt I have no idea what have of these messages mean. This is less clear to me (probably because I'm used to the old messages) than the 'wd' messages. Also, like others, I'm getting that 'ata_command: timeout waiting for interrupt' at the end. -Steve ----- Original Message ----- From: Mike Smith <msmith@FreeBSD.ORG> To: Julian Elischer <julian@whistle.com> Cc: <current@FreeBSD.ORG> Sent: Wednesday, December 08, 1999 1:56 PM Subject: Re: HEADSUP: wd driver will be retired! > > > > because it doesn't support the chipsets that the old one does. > > (namely the 200 or so lines of support in pci_ide.c needed for the Cyrix > > GXM series). > > > > You shouldn't remove a function until it has been properly replaced. > > A very simple concept some people seem to have trouble grasping. > > Actually, that's not at all correct.
