=== lamont screams at amd64
lamontwith an amd64 kernel, and i386 user space, xsane fails to find the scanner - "device busy"04:12
mjg59Yay 32-bit ioctl emulation04:12
mjg59That stuff's always broken04:13
lamontsigh.  any trivial way to find _which_ ioctl is b0rked?04:13
BenCwhich is why I am hesitant to provide an amd64 kernel for i38604:14
BenClamont: check dmesg04:14
lamontI suppose I could always use 2.6.15, eh?04:14
BenCwhy not just use i386 kernel?04:14
BenCor 64-bit userspace :)04:14
lamontoh, yeah. plenty of them.04:14
lamonti386 kernel --> double time rate04:14
lamontiz mother board issue that's "fixed" in amd64 kernel, but not in i38604:15
BenCuse noapictimer04:15
lamontthat's only implemented in x86_6404:15
BenCnah, it worked for my sempron notebook (32-bit k8) with -k7 kernel04:15
lamontdidn't work for  me.04:15
lamont[  225.362891]  ioctl32(xsane:10063): Unknown cmd fd(8) cmd(c00c5512){00} arg(ffff88c0) on /proc/bus/usb/003/00104:15
BenCweird, did for me04:15
BenCwell, you know it's a USB ioctl, just parse cmd to find which one (referencing usb ioctl headers)04:16
BenCgotta run04:16
lamontkernel          /boot/vmlinuz-2.6.12-9-386 root=/dev/sda1 ro quiet splash noapictimer04:16
lamontlike that, I wonder?04:16
=== lamont gives noapictimer another chance
lamontbrb04:17
mjg59noapic nolapic also ought to work04:17
lamontmjg59: which should I use?04:17
mjg59If noapictimer doesn't work, try noapic nolapic04:17
lamont"noapic nolapic" or each one separately in turn?04:17
mjg59Both parameters at once04:18

=== lamont wonders what all he needs to install in order to have a working breezy/2.6.15 system
=== cjb has a working dapper/2.6.15 amd64 system, fwiw.
infinityMeh.05:38
=== crimsun [n=crimsun@pdpc/supporter/silver/crimsun] has joined #ubuntu-kernel
cjblamont: Wait, you're seeing double-time?  Have you tried acpi_disable_pin_1, or whatever it's called?05:39
=== pappan [n=garbage@bgepxyout-02.asiapac.hp.net] has joined #ubuntu-kernel
cjbOh, I see, you're seeing doubletime with noacpi.  I'm not helping, then.05:40
infinitymjg59: Feel like thinking more about my scaling problem?05:40
infinityfor i in *freq; do echo -n "$i: "; sudo cat $i; done05:42
infinitycpuinfo_cur_freq: 80000005:42
infinitycpuinfo_max_freq: 200000005:42
infinitycpuinfo_min_freq: 80000005:42
infinityscaling_cur_freq: 80000005:42
infinityscaling_max_freq: 80000005:42
infinityscaling_min_freq: 80000005:42
infinityThat would appear to be problematic...05:42
mjg59Hm.05:46
mjg59Wonder what scaling_max_freq means05:46
infinityAnd for reference:05:46
infinityscaling_available_frequencies: 2000000 1600000 1333000 1066000 80000005:46
infinitySo, it sees all the available frequencies, then sets the max to 80000005:47
infinityAFAICT.05:47
infinityBenchmarks seem to bear this theory out (it's slow as hell right now)05:47
mjg59On 2.6.5-11, I've got scaling_max_freq: 120000005:48
mjg59Can you echo 2000000 to scaling_max_freq?05:48
infinityThat's on a 1.2GHz X40 though, right?05:49
mjg59Yeah05:49
infinity(base)root@cthulhu:/sys/devices/system/cpu/cpu0/cpufreq # echo 2000000 > scaling_max_freq05:49

infinity80000005:49
mjg59Right05:50
mjg59Sounds Dothan specific, then05:50
mjg59What cpufreq module do you have loaded?05:50
infinitycentrino.05:50
infinitySame as always, afaik.05:50
mjg59Can you stop powernowd, unload that and load acpi-cupfreq?05:51
=== pappan [n=garbage@bgepxyout-02.asiapac.hp.net] has joined #ubuntu-kernel
infinityHrm.  How can I see what processes are using a module?05:52
infinity(Can't unload speedstep_centrino, in use)05:53
mjg59Are you still in /sys/devices/system/cpu/cpu0/cpufreq ?05:54
infinityOh, I could be that retarded...05:54
mjg59Yay kernel refcounting05:55
infinityErr, no.  Leaving did no good.  Still a refcount of 1.05:55
mjg59You didn't cd there, su and then cd out, did you?05:57
infinityNo, lsof confirms I'm not that dumb.05:58
mjg59Ok05:58

mjg59Hm. No, it seems I can't unload mine either05:59
mjg59Bloody thing05:59
infinityNot sure why anything would hold a handle open on /proc/cpuinfo, but that shouldn't matter, I hope.05:59
