Sorry again perry, I just re-booted to try your idea, I have oe of those low end BOISs with no options for performance tweaking, I reset the defaults anyways, but it didn't help :(
I also tried ide=nodma on the off chance that that would help... booted faster, but still with the stops. Drats! |
truthfatal:
Now I'm curious - have you tried any other distributions on this box? If so, do they exhibit the same problem? I would recommend trying (probably) Gentoo in this case, as (I think) they use a "closer to vanilla" kernel than some others (but I may be wrong); perhaps one of the Slackware derivatives would be a good choice to try too. If one of the others works fine, then run a diff on the kernel configs and start looking for likely suspects (feel free to post the diff here). |
I have used Ubuntu (7.04) without this problem... their kernel is pretty heavily patched as far as I recall though, I was about to go dig up a .config from them somewhere to do exactly as you suggest.
I will probably try a few LiveCDs as well. Hopefully I can find a Slack based distro if I have to move away from "real" Slackware. I somewhat dislike the non-slack-like package managers. |

I'm actually in the process of burning a KateOS liveCD (just finished Zenwalk and Gentoo disks, I think I'll give my CPUs a rest after that.
hwmon is detecting my processors at ~55 Celsius after about 45 minutes straight at about half throttle. I do have frequency scaling enabled so they throttle down to 800Mhz each when idle. also, I keep my laptop actually on my lap (at the moment, not always)and I'm not noticing any significant warmth coming off of this thing. (when I'm not working the machine 'hard' my cputemp is usually around 30 degrees... which doesn't seem that excessive for a notebook.) I'll definitely look into my hardware as a source of my issue. |

so I did ide=poll instead of idle=poll I feel like a moron, but I'll survive. Thank you very much rworkman, and PiterPunk! (and also http://ronware.org/wiki/Pub:Linux_on_the_Acer_5100-5033 for having similar advice in a different font!) Oh yeah, Problem solved. |

I have to pass noapic nolapic_timer to the kernel. My understanding of the issue is that there's currently an SMP bug when using a 32bit mode kernel on a 64bit processor. however, all information on this seems to have vanished out of google. In fact, I can find almost no references to Toshiba A215-S4807s running linux at all now. I can trigger the same problem in the most current kernel. It would be great if it's a performance bug, but my BIOS doesn't have those settings. I believe it to be an IOAPIC / interrupt bug. It's disturbing. |
