hardware detection slow..?
 
I've a question regarding SuSe 9.2. I like it very much, but the hardware detection is very slow. It takes a minute for SuSE to detect+mount my usb-pen/digicam. Is this happening to everybody else too, or is there something (maybe ACPI) that I can re-configure?

how recent of a kernel are you running?

Just and FYI: 2.6.12 gave me usb problems with the usbfs filesystem, but 2.6.11.x have been fine.

yapp 07-02-2005 06:19 AM

I'm running 2.6.8-24.16-default (which is off course patched by SuSE)

musicman_ace 07-02-2005 07:16 AM

I'd suggest the 2.6.11 releases. Give it a whirl, if it doesn't help then its one less option that could be right.

Thanks. I'll try that, the SuSE 9.3 mirrors appear to have rpm-packages for 2.6.11 :)
Although I don't think this is a permanent solution, as it will kill the online security updates.

Ok, let me rephrase that. Stop using RPM kernels and download the source from a kernel.org mirror.

I think hardware detection on linux is always slow. Compiled kernel or SuSE's default.

My gentoo laptop boots to runlevel 3 in 30 seconds from power on to prompt. All hardware drivers are built-in except for the video driver and I usually have the pcmcia wireless card attatched. I haven't used SusE for a while to know if they are slow at coldplugging hardware.

You could disable any services that start automatically that aren't necessary.
<edit>
Most people don't check their logs regularly, so you could disable that although my advice would be to keep it and check your logs regularly.

No but thanks. :)
I ditched Gentoo in favour of SuSE.

Having used Gentoo and Slackware for both 1 year myself, I compiled all my kernels (and a lot of packages) from source in the past. I used to be a Gentoo fan myself, but compiling a kernel each time yourself takes a lot of time and resources (cpu power, having a slow system, patching security holes manually, spending time following security bulletins) In my case binary packages outweight the "advantages" of compiling from source.

Already did that.

Maybe. That would be unfortunate.

I have a "hwscan" process lagging the entire system. But maybe it's my hardware, so I'd like to know if anyone else experiences the same problems. (with hwscan, or SuSE 9.2)

Err... RPM is just the same thing but in a different format, i.e same files except they're packaged in an rpm. I highly doubt an rpm based kernel slows down one's sister, inact I do doubt it.

The only thing is it's generic *made for most systems in general..not yours*...so I don't think it would be very optimized. You could disable un needed stuff by compiling it yourself. However, I really don't think you'd feel much difference.

I have 1GB of RAM and a 3.06GHZ HT CPU, I couldn't be botherred really ;-).

I did a "make cloneconfig && make menuconfig" with the official SuSE kernel sources. They are optmized for i586 machines and up.

SuSE compiles all drivers as modules, meaning they are not loaded until you use them. There is no need to disable all kinds of stuff, there isn't much sitting in the way. Besides, it ain't amusing if you need to recompile your kernel because you want to use your floppy driver or experiment with NFS. :p Been there, done that, got the T-shirt.
