(If this is what you wanted, I couldn't get it from > your last message and did not follow the thread too closely.) How would I remove ISA ata controllers? I am running FreeBSD-5.1 so my config looks like this: $ grep -i ata /sys/i386/conf/TEAM2 # ATA and ATAPI devices device ata device atadisk # ATA disk drives device atapicd # ATAPI CDROM drives #device atapifd # ATAPI floppy drives #device atapist # ATAPI tape drives options ATA_STATIC_ID #Static device numbering > > ... > > atapci0: <Promise PDC20246 UDMA33 controller> > > port 0xd400-0xd41f,0xd804-0xd807,0xe000-0xe007,0xe404-0xe407,0xe800-0xe807 > > irq 14 at device 5.0 on pci0 > > ata2: at 0xe800 on atapci0 > > ata3: at 0xe000 on atapci0 > > [ snip ] > > ... > > ata0 at port 0x3f6,0x1f0-0x1f7 irq 14 on isa0 > > ata1 at port 0x376,0x170-0x177 irq 15 on isa0 > > ... > > ad4: 8223MB <ST38410A> [16708/16/63] at ata2-master UDMA33 > > Do you see the "ata0 ... on isa0" connection/binding? No. Like I said, I only editted out irrelevent stuff: $ grep -i ata /var/run/dmesg.boot atapci0: <Promise PDC20246 UDMA33 controller> port 0xd400-0xd41f,0xd804-0xd807,0xe000-0xe007,0xe404-0xe407,0xe800-0xe807 irq 14 at device 5.0 on pci0 ata2: at 0xe800 on atapci0 ata3: at 0xe000 on atapci0 ata0 at port 0x3f6,0x1f0-0x1f7 irq 14 on isa0 ata1 at port 0x376,0x170-0x177 irq 15 on isa0 ad4: 8223MB <ST38410A> [16708/16/63] at ata2-master UDMA33 > Even if > there is no hardware to handle, the logical number is allocated. > So the first auto recognised (i.e. additional) controller cannot > live there, too. This is very similar to the "Why does my (one > and only) NE2K PCMCIA clone show up as ed1?" question, while > people have ed0 bound to an (absent) ISA card in their config > as it is in GENERIC. Well, comming up as ed1 makes sense for a removable device, and especially seeing as how (fbsd-4.x) GENERIC specifically allocates ed0. Reserving ata0 and ata1 for hardware that is there makes sense. Reserving them when there is no hardware, and no specific allocation, doesn't. But the main problem is that the kernel thinks that there are devices on ata0 and ata1 when there are clearly not: $ vmstat -i interrupt total rate stray irq7 1 0 ahc0 irq11 14 0 dc0 irq10 31456 0 ata0 irq14 215722 0 <-- should be ata2 ata1 irq15 9656 0 <-- should be ahc1 atkbd0 irq1 2 0 fdc0 irq6 4 0 clk irq0 60125688 99 rtc irq8 76964395 128 At least my devices work at irqs 14 & 15. I feel sorry for Vladislav. -- :{ andyf@speednet.com.au Andy Farkas System Administrator Speednet Communications http://www.speednet.com.au/
