[12:09] last comment on bug 112104 specifically [12:49] popey: Like I said, the lack of throttling isn't a problem [12:50] So regardless of anything else, the bug is mistitled :) [12:50] heh [12:51] suggestions welcome then [12:53] But yeah, the scaling stuff looks utterly funted [12:53] What hardware is this? [12:53] tosh tablet laptop [12:53] Other than that, the failures are fairly harmless [12:53] Does Windows scale it correctly? [12:54] it doesnt feel quick though [12:54] dunno, dont use windows [12:54] Right, the scaling brokenness is probably killing performance [12:54] If you run something cpu intensive, do the values in /proc/cpuinfo rise? [12:55] it always sits at 2GHz [12:55] never changes [12:55] Yeah, that's fucked [12:55] my apologies if i disappear.. on ropey wifi at UDS [12:56] Also, don't use powernowd directly - the init script should just be setting up ondemand and leaving it up to the kernel [12:56] ok [12:56] Can you try unloading speedstep_centrino and load acpi-cupfreq instead? [12:57] sure [12:57] speedstep_centrino isnt currently loaded [12:57] ... [12:57] Ok, so that's a pretty poor sign to begin wth [12:57] acpi_cpufreq is [12:57] Ok, that might explain it [12:57] In that case, try unloading acpi-cpufreq and load speedstep-centrino [12:58] ok [12:58] FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.20-15-generic/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device [12:58] Anything appear in dmesg then? [12:58] no, but I get a lot of these all the time:- [12:59] [ 5424.824000] APIC error on CPU0: 40(40) [12:59] [ 5424.824000] APIC error on CPU1: 40(40) [01:00] Ok. I think you'll need to work with Ben to figure out why speedstep-centrino isn't working. In theory, the acpi_cpufreq stuff should work. [01:00] heh, spoke to ben the other day, he said "it's broken" [01:00] Well, that's the obvious conclusion [01:00] well, actually said "sounds liek hardware failure" [01:01] What was the bios option that you changed actually called? [01:01] sorry, can't remember, it was something about cpu scaling [01:01] but not the word scaling [01:02] will check in the morning when i reboot [01:02] It may be that that needs to be enabled [01:02] is this the kind of thing that might be fixed by a bios update or is it more likely to be a kernel thing do you think? [01:02] Sounds like a bios thing [01:03] ok, will re-enable when i boot in the morning and try the speedstep_centrino module, thanks === crimsun_ [i=crimsun@nat/redhat/x-e46d6b4d7f3c0637] has joined #ubuntu-laptop [01:11] meh, couldn't waity [01:11] it is called "Dynamic CPU Frequency Scaling" - I had it set to "Always high", now it is "Dynamically Switchable" [01:11] Ok [01:11] (last option is "always low") [01:12] "Dynamically Switchable" sounds like the right value [01:12] cpuinfo says 1GHz [01:12] Ok. If you do something that loads the CPU (like dd if=/dev/zero of=/dev/null) does that rise? [01:12] alan@mother:/proc/acpi/processor/CPU0$ cat throttling [01:12] [01:12] one mo [01:13] yes [01:13] cpuinfo says 2GHz now [01:13] Ok. So that works. [01:13] throttling isn't the same thing as frequency scaling [01:13] and back to 1Ghz [01:13] ah, ok [01:14] Throttling just drops the clock rate of the processor. It doesn't drop the voltage. As a result, it's entirely useless for anything other than emergency limitation, and even then scaling is preferable. [01:14] right [01:14] So don't worry about the lack of throttling [01:14] wilco [01:14] Based on your descriptions, everything now sounds fine except for the oddly low performance [01:15] Which is somewhat trickier to track down... [01:15] Your laptop probably has less cache than the desktop machine, but I would expect that to make a huge difference in the case you're describing [01:15] kind of a bummer when i was hoping to do some cpu intensive stuff with this thing :( [01:15] I'd recommend some more solid benchmarking [01:16] ok, the unix bench thing? [01:16] Byte Unix Benchmark [01:16] For instance [01:16] I've never done any heavy CPU benchmarking, so... [01:16] http://hants.lug.org.uk/cgi-bin/wiki.pl?ByteUNIXBenchmark is the kind of thing [01:17] which seems relatively comprehensive [01:19] thanks for the time spent on this mjg59, another beer in the nudge bank === crimsun__ [i=crimsun@nat/redhat/x-76e70ccd9c552b69] has joined #ubuntu-laptop === defendguin [n=supertux@cpe-72-181-7-135.houston.res.rr.com] has joined #ubuntu-laptop === tritium [n=tritium@ubuntu/member/tritium] has joined #ubuntu-laptop === robitaille [n=daniel@ubuntu/member/robitaille] has joined #ubuntu-laptop === ewanm89 [n=ewanm89@host81-151-191-133.range81-151.btcentralplus.com] has joined #ubuntu-laptop === Infecto [i=infecto@hydrozagadka.com] has joined #ubuntu-laptop === Fahuadai [i=mark@wrl-100001101101001.d.port.ac.uk] has joined #ubuntu-laptop [12:58] I have heard that 7.04 has inproved support for broadcom wireless cards including the bcm43** series.
