You don't have to test 16 modules one at a time, although you will have to run the test more than once: Remove half (8) of the memory modules. Ensure what is left is installed in the slot combination recommended by the MoBo manufacturer. Test these. If no fault is found swap them for the other half. As soon as a fault is reported, remove half of this batch (4) and install the other 4 as recommended by the MoBo manufacturer. Rinse and repeat. This way you will eventually isolate the dodgy DIMM module, by running the test fewer than 16 times. Usually errors show in the first round of tests, but some times you may need to wait for more than 8 passes. Before you start any of this it is a good idea to just reseat the modules one at a time in case you have some dirt or oxidisation in any of the contacts. That could save a lot of hours ... Make sure you have marked clearly which batches have showed no errors - if you mix them up you will have to start from the beginning.

Is the above the right path to follow? [Humongous snip] Ah, you need first the drivers then. Don't bother with out-of-tree drivers. Try (directly in your kernel) USB_VIDEO_CLASS (a.k.a. UVC), CONFIG_USB_GSPCA, and if that doesn't work enable all of CONFIG_USB_GSPCA_*. Mine works only with CONFIG_USB_GSPCA. After loading the modules, or booting with the new kernel, see if you have /dev/v4l (it's a dir). Then any modern software (e.g., Cheese or google-talkplugin) will autodetect the camera.

Thank you canek (and walt, james, and eroen) but I didn't make clear the
level of my ignorance. I have never used a webcam, but I recently
became a grandfather so figured I should learn. I must need a driver
for the camera. According to lsusb I have
Bus 001 Device 004: ID 0c45:646b Microdia
(the 400 line verbose output is at the end of this msg).
But I get no hits on google for that number (there are some close)
gentoo-wiki.info lists several webcams but not mine then ends with
Other
If you can't identify the make or model or your webcam, try these
drivers:
media-video/gspcav1: supports many webcams based on various
chipsets. List of supported devices at
http://mxhaard.free.fr/spca5xx.html
media-video/linux-uvc: supports many webcams following the UVC

available.
>From the list at linux-uvc.berlios.de I see that 0c45 is Sonix

media-video/linux-uvc.

[gentoo-user] OT - memory testing
Got a question from a friend of mine who works in IT. He's very new to Linux. Here is his question: "Have you ever found a program in linux that allows you to locate bad dims if you have faults? I’ve tried memtest86, memconf, memtester and none of them can point out what slot on the motherboard has the bad RAM. I know usually you just plug in one at a time. But memtest86 takes hours and I have…wait for it….16 slots to test DIMs on for this specific server with memory failure." Any ideas? Is it even possible for the software to know which slot the bad memory is in? He isn't using Gentoo, I think he's on Ubuntu. If you can suggest software we'll deal with the installation. Thanks very much - Skippy

I did asked for the difference, not the whole damn lot. You have to do
some of the work yourself.
However, a quick glance shows this
/lib/udev/rules.d/60-persistent-serial.rules:SUBSYSTEM!="tty",
GOTO="persistent_serial_end"
/lib/udev/rules.d/60-persistent-serial.rules:KERNEL!="ttyUSB[0-9]*|ttyACM[0-9]*",

Which package installed that file and what does it contain?
I compared the two files (using meld) 60-persistent-serial.rules
from two systems and they are identical.

Packages that need a particularly large amount of space usually check its availability at the start of the emerge process. There's nothing to stop you using tmpfs for the default PORTAGE_TMPDIR and resetting it to somewhere on your drive for particularly large packages, using package.env Put "cat/pkg tmpondisk.conf" in /etc/portage/package.env and "PORTAGE_TMPDIR=/a/disk/dir" in /etc/portage/env/tmpondisk.conf -- Neil Bothwick Engineers do it with less resistance. signature.asc Description: PGP signature

[gentoo-user] tmpfs for portage: how much?
Hi Gentoo-users, I would like to use tmpfs for all the package-compilation to spare my SSD from too many writing-cycles, but I can not guess how much do I need. I'm rather limited with RAM, if I use more than 512MB for /var/tmp/portage, my server lowers buffers/cache to nearly zero and starts swapping... So what do your think? Would it be enought to have 512MB for packages like GCC, Apache, MySQL, Sendmail, Bind? These are the biggest, rest are much smaller...

Both machines are amd64 and have similar setup including the same kernel verion: linux-3.10.7-gentoo-r1 The machine that identify ttyS0 as: crw-rw 1 root dialout 4, 64 Jan 21 09:04 /dev/ttyS0 has in: /lib/udev/rules.d/50-udev-default.rules SUBSYSTEM=="tty", KERNEL=="ptmx", GROUP="tty", MODE="0666" SUBSYSTEM=="tty", KERNEL=="tty", GROUP="tty", MODE="0666" SUBSYSTEM=="tty", KERNEL=="tty[0-9]*", GROUP="tty", MODE="0620" SUBSYSTEM=="vc", KERNEL=="vcs*|vcsa*", GROUP="tty" KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*", GROUP="dialout" The machine that identify ttyS0 as: crw-rw-rw- 1 uucp dialout 4, 64 Jan 20 14:30 /dev/ttyS0 has in: /lib/udev/rules.d/50-udev-default.rules SUBSYSTEM=="tty", KERNEL=="ptmx", GROUP="tty", MODE="0666" SUBSYSTEM=="tty", KERNEL=="tty", GROUP="tty", MODE="0666" SUBSYSTEM=="tty", KERNEL=="tty[0-9]*", GROUP="tty", MODE="0620" SUBSYSTEM=="vc", KERNEL=="vcs*|vcsa*", GROUP="tty" KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*", GROUP="dialout" So the settings is identical, and I don't remember entering my own rules for ttyS0. Though one server is running hylafax the other doesn't. -- Joseph

The most significant difference is that cairo might stop working if lzo is removed after cairo was built*. To resolve this, the Gentoo maintainer recently added lzo to the dependencies to make sure lzo is not removed. If you rebuild cairo after installing lzo, some obscure feature might be enabled, but the maintainer seems to think this is not significant, and did not increase the revision number to force a rebuild everywhere. http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/x11-libs/cairo/cairo-1.12.14-r4.ebuild?r1=1.12&r2=1.13 * In most cases, that's prevented by the (now default-on) preserve-libs FEATURE in portage. Non-default setups aren't necessarily as lucky. > $ equery d makedepend > * These packages depend on makedepend: > app-cdr/cdrtools-3.01_alpha17 (x11-misc/makedepend) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-cdr/cdrtools/cdrtools-3.01_alpha17.ebuild?r1=1.13&r2=1.14 A similar change (though no bug :-( ), except makedepend is a build-time-only dependency, and not strictly required after cdrtools is built. I will not venture to guess what the consequences of building cdrtools without makedepend installed are, but since you somehow got it installed at some point, there is either a fallback of some sort, or you had it installed for other reasons. Whether this build-time dependency (DEPEND) change causes makedepend to be installed after the fact is governed by the --with-bdeps switch to emerge, check the man page for details. > But cairo was last emerged 16 days ago and cdrtools last September, > so why have these dependencies suddenly appeared today? Portage has > been at 2.2.7 since last year too. Emerge --info doesn't mention lzo. By default, in order to let maintainers fix issues, portage calculates what to install based on the *current* package ebuilds, rather than the ebuild at the time a package was installed. While this can be disabled by the user, maintainers will expect it to work, so best not ;-) > I can't think of anything else that might have changed, unless new > dependencies have been shoved into the ebuilds.

[gentoo-user] New dependencies suddenly popping up
Hello list, After my daily sync today, portage wanted to emerge two new packages: dev- libs/lzo and x11-misc/makedepend. No other packages were mentioned. Odd, I thought, so: $ equery d lzo * These packages depend on lzo: [...] X11-libs/cairo-1.12.14-r4 (dev-libs/lzo) $ equery d makedepend * These packages depend on makedepend: app-cdr/cdrtools-3.01_alpha17 (x11-misc/makedepend) But cairo was last emerged 16 days ago and cdrtools last September, so why have these dependencies suddenly appeared today? Portage has been at 2.2.7 since last year too. Emerge --info doesn't mention lzo. I can't think of anything else that might have changed, unless new dependencies have been shoved into the ebuilds. Does that sort of thing happen in a well run family? -- Regards Peter
[gentoo-user] Kworker use >80% of CPU
Hi. After computer starts, in top, I have kworker used 80% of cpu. It is a problem with ACPI IRQs, because it come to normal after i run echo "disable" > /sys/firmware/acpi/interrupts/gpe08 > echo "disable" > /sys/firmware/acpi/interrupts/gpe1B > I tried to do it on startup by adding script to /etc/local.d/ but it doesn't help. Now I have 3.10.24-gentoo kernel, generated by genkernel, but I noticed this problem few month ago. Can you help me? С уважением, Клочков Глеб

You are not compiling it, merely unpacking it. No matter how many times you do this, the binaries it installs will not change.
