there is no atapi watchdog code, meaning if the atapi driver wedges you are kinda out of luck. in my clueless search for something to do i've been looking at this and comparing it to linux code for atapi handling, but um, i kinda stink at this. someone said they'd fix it sooner or later. from what i see the problem is that if anything tries to reset an atapi device all it does is call the bus_wait command on the bus or something, not very effective. and there is no timer or anything to make sure atapi requests are working or not. -Alfred On Wed, 3 Jun 1998, Sergey Shkonda wrote: > I have BIG problem with xmcd 2.3 player: > Disk i/o stopped when I press 'play' button. > > I think, It's wdc, wcd or atapi bug. > Can anybody help me to correct this problem ? > > > >FreeBSD 2.2.6-RELEASE #1: Tue May 5 22:09:45 EEST 1998 > root@bcs3.bcs.zaporizhzhe.ua:/var/scratch/src/sys/compile/BCS > CPU: AMD-K6tm w/ multimedia extensions (166.45-MHz 586-class CPU) > Origin = "AuthenticAMD" Id = 0x562 Stepping=2 > Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX> > real memory = 33554432 (32768K bytes) > avail memory = 30859264 (30136K bytes) > Probing for devices on PCI bus 0: > chip0 <Intel 82439TX PCI cache memory controller> rev 1 on pci0:0:0 > chip1 <Intel 82371AB PCI-ISA bridge> rev 1 on pci0:7:0 > chip2 <Intel 82371AB IDE interface> rev 1 on pci0:7:1 > chip3 <Intel 82371AB USB interface> rev 1 int d irq 11 on pci0:7:2 > chip4 <Intel 82371AB Power management controller> rev 1 on pci0:7:3 > ed0 <NE2000 PCI Ethernet (RealTek 8029)> rev 0 int a irq 10 on pci0:9:0 > ed0: address 00:4f:49:02:eb:17, type NE2000 (16 bit) > vga0 <VGA-compatible display device> rev 22 int a irq 9 on pci0:10:0 > ed1 <NE2000 PCI Ethernet (Compex)> rev 10 int a irq 12 on pci0:11:0 > ed1: address 00:80:48:fd:eb:a0, type NE2000 (16 bit) > ed2 <NE2000 PCI Ethernet (ProLAN)> rev 0 int a irq 11 on pci0:12:0 > ed2: address 00:40:95:00:52:f0, type NE2000 (16 bit) > Probing for devices on the ISA bus: > sc0 at 0x60-0x6f irq 1 flags 0x2 on motherboard > sc0: VGA color <13 virtual consoles, flags=0x2> > lpt0 at 0x378-0x37f irq 7 on isa > lpt0: Interrupt-driven port > lp0: TCP/IP capable interface > sio0 at 0x3f8-0x3ff irq 4 on isa > sio0: type 16550A > sio1 at 0x2f8-0x2ff irq 3 on isa > sio1: type 16550A > wdc0 at 0x1f0-0x1f7 irq 14 flags 0x80ff80ff on isa > wdc0: unit 0 (wd0): <WDC AC2850F>, 32-bit, multi-block-16 > wd0: 814MB (1667232 sectors), 1654 cyls, 16 heads, 63 S/T, 512 B/S > wdc0: unit 1 (atapi): <SAMSUNG CD-ROM SCR-2431/1.03>, removable, intr, dma, iordy > wcd0: 343/3445KB/sec, 382KB cache, audio play, 255 volume levels, ejectable tray > wcd0: 120mm audio disc loaded, unlocked > wdc1 at 0x170-0x177 irq 15 flags 0x80ff80ff on isa > wdc1: unit 0 (wd2): <QUANTUM FIREBALL ST2.1A>, 32-bit, multi-block-16 > wd2: 2014MB (4124736 sectors), 4092 cyls, 16 heads, 63 S/T, 512 B/S > fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa > fdc0: FIFO enabled, 8 bytes threshold > fd0: 1.44MB 3.5in > fd1: 1.2MB 5.25in > npx0 on motherboard > npx0: INT 16 interface > > -- > Sergey Shkonda (serg@bcs.zaporizhzhe.ua) > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hackers" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
