From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christopher Nielsen To: 9fans@cse.psu.edu Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Subject: [9fans] 53C896 Date: Wed, 25 Oct 2000 22:56:49 -0700 Topicbox-Message-UUID: 1dcbe79e-eac9-11e9-9e20-41e7f4b1d025 It seems the fileserver kernel isn't all that happy with the built-in SCSI controller on my MB (Symbios 53C896). I'm not all that surprised from what I've seen in the archives, but I decided to give it a go, anyway. I've re-tooled the emelie kernel with extra debugging. The output of which is below. Any ideas on where to start with better support for this controller on the fileserver? Jim, Nigel, do you have any patches that would be useful? I'm more than happy to be a guinea pig for patches and/or dive into the code. --- begin boot and debug output --- ether#0: i82557: port 0xEE80 irq 9: 00E081112729 sd53c8xx: SYM53C896 rev. 0x05 intr=5 command=2100117 sd53c8xx: SYM53C896 rev. 0x05 intr=11 command=2100117 sd53c8xx: bios scntl3(77) stest2(00) sd53c8xx: bios scntl3(77) stest2(00) found 9PCFS .GZ attr 0x0 start 0x11e len 162209 .gz......................162209 => 229633+38836+172528=440997 entry: 80100020 CPU is a 882 MHz P6 (cpuid: AX 0x0683 DX 0x383fbff) ether0: i82557: 0Mbps port 0xee80 irq 9: 00e081112729 scsi#0: SYM53C896 rev. 0x05 intr=5 command=0117 scsi#0: local SCRIPT ram enabled ncr53c8xx: tpf=12 scf=1.0 xferp=4 mhz=20.000 ncr53c8xx: tpf=15 scf=1.0 xferp=5 mhz=16.667 ncr53c8xx: tpf=18 scf=1.5 xferp=4 mhz=13.889 ncr53c8xx: tpf=23 scf=1.5 xferp=5 mhz=10.870 ncr53c8xx: tpf=25 scf=2.0 xferp=4 mhz=10.000 ncr53c8xx: tpf=31 scf=2.0 xferp=5 mhz=8.065 ncr53c8xx: tpf=37 scf=3.0 xferp=4 mhz=6.757 ncr53c8xx: tpf=43 scf=2.0 xferp=7 mhz=5.814 ncr53c8xx: tpf=46 scf=3.0 xferp=5 mhz=5.435 ncr53c8xx: tpf=50 scf=4.0 xferp=4 mhz=5.000 ncr53c8xx: tpf=62 scf=4.0 xferp=5 mhz=4.033 ncr53c8xx: tpf=74 scf=4.0 xferp=6 mhz=3.379 ncr53c8xx: tpf=87 scf=4.0 xferp=7 mhz=2.874 ncr53c8xx: tpf=100 scf=4.0 xferp=8 mhz=2.500 ncr53c8xx: tpf=112 scf=4.0 xferp=9 mhz=2.233 ncr53c8xx: tpf=125 scf=4.0 xferp=10 mhz=2.000 ncr53c8xx: tpf=137 scf=4.0 xferp=11 mhz=1.825 scsi#0: ncr53c8xx: port 0xfebe8000 irq 5 ncr53c8xx: int sist = 0002 ncr53c8xx: int end 0 iobufinit 29233 buffers; 3659 hashes mem left = 44744703 out of = 536870912 nvr read found plan9.nvr attr 0x0 start 0x11d len 512 ** NVR key checksum is incorrect ** ** set password to allow attaches ** config: config w1.0.0 config: service thoth config: filsys main c[w1.<0-1>.0]j(w6w<4-5>)(l<0-37>l<38-75>) config: filsys dump o config: ip 199.239.183.141 config: ipgw 199.239.183.129 config: ipauth 199.239.183.140 config: ipmask 255.255.255.192 config: ream main config: end sysinit config w1.0.0 devinit w1.0.0 stack trace of 1 0x8012328f 0x80135285 0x80126e53 0x80126dec 0x801103dc 0x80126afc 0x801287e9 0x80106150 0x80106150 0x8012f6b1 0x80105c9f 0x80105bf7 0x80100254 0x801003f1 0x801178f2 0x801178f2 0x80117580 0x8010039b 0x80110008 0x80117927 0x8010967c 0x8010967c 0x8010999d 0x80100b76 0x801241df 0x8010d291 0x80125735 0x80105cb2 0x801009ae 0x80123c1b 0x80123f6a 0x80123f49 0x80123e2d 0x801178f2 0x80117580 0x801071bc 0x80123b91 0x80110008 0x80101033 0x80100f8d 0x80100254 0x80100f31 0x80123e2d 0x801241df 0x80123d36 0x80100254 0x80105bf7 0x8010967c 0x801241df 0x8010065d 0x801175d3 0x80105bf7 1196 stack used out of 4000 panic: scsiio: device = w1.0.0 cpu 0 exiting --- end boot and debug output --- -- Christopher Nielsen cnielsen@pobox.com
