A long time ago, circa FreeBSD 4.3, my Sony PCMCIA CD-ROM drive with brain-damaged Teac ATA controller drive worked, and the people were content and all was right with the land. Then my 4.4 CD set arrived, and I was disappointed to find the install kernel would lock up after the driver was probed. Complaints were made and epithets were hurled, and lo, in 4.5-RELEASE, all was well once again. Then came 4.6-RELEASE, and it was broken again. Then came 4.6.2, and it was still broken. And in 4.7. And 4.8. And 5.0. (Yeah yeah, shut up.) I just got my 5.1-RELEASE CDs and guess what? My CD-ROM drive STILL doesn't work!!! Guys, there's nothing more frustrating than getting a brand new CD set in the mail and not being able to install via CD. So I'm not leaving it up to chance anymore. I have a patch to make my drive work here: http://www.freebsd.org/~wpaul/ata-card.c.diff-5.1 I have no idea what the altio port remapping goop in ata_pccard_probe() is supposed to accomplish, but I'm telling you all right now, it doesn't work with my drive. I have specifically added to code to skip the remapping for drives with the product string of "NinjaATA-" (the problem with the Teac controller is that its vendor/product ID is 0xffff/0xffff, so there's really no better way to indentify it). This patch changes this: ata2: < NinjaATA-> at port 0x180-0x187,0x386-0x387 irq 9 function 0 config 33 on pccard0 device_probe_and_attach: ata2 attach returned 6 Into this: ata2: < NinjaATA-> at port 0x180-0x187,0x386-0x387 irq 9 function 0 config 33 on pccard0 acd0: CDROM <CD-224E> at ata2-master PIO4 Now, I'm sending out this notification that I _WILL_ check this patch in before I leave the office today. I'm not asking for permission. I've been waiting for half a dozen releases for this to get fixed. When 5.2-RELEASE arrives in my mailbox, it _WILL_ install from CD-ROM on my laptop or so help me I will find the responsible parties and force them to listen to RMS sing "Free The Software" -- _live_ -- until their ears bleed. I have tested this patch. It compiles. It works. I can mount CDs successfully and transfer stuff from them to my heart's content. I've reduced the change down to the absolute minimum and insured that it won't affect any other drives except mine. It's going in. Period. I am not leaving it up for debate, because if I do, all that will happen is that people will argue over what the more "correct" fix should be, and at this point I _just_ _don't_ _care_. I want my drive to work, and this does it. Understand? Good. This concludes my announcement. Thank you all for your attention. Don't forget to tip the waitress. -Bill P.S.: Be sure to join us next time when I ream out whoever it was that broke support for my 3Com 3c575C cardbus ethernet NIC. -- ============================================================================= -Bill Paul (510) 749-2329 | Senior Engineer, Master of Unix-Fu wpaul@windriver.com | Wind River Systems ============================================================================= "If stupidity were a handicap, you'd have the best parking spot." =============================================================================
