Meeting tonight, Martha's Exchange.
Hey, all -- a reminder about the meeting tonight; 6:00 for food, 7:00 for meeting. But... It occured to me that today's St. Patrick's day, and, yes, Martha's is a bar. So, even moreso than usual, it probably behooves me to try for a headcount, and make a reservation for thems that want to eat. Please get back to me if you're planning on being there for grub, and I'll set things up with Martha's. Thanks, and look forward to seeing you guys! -Ken ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
High memory kernel support
I have a server that started throwing the following error the other day: kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0) We run some pretty memory intensive apps, and from looking at various logs it appears the machine ran out of memory space and started shutting down services. I was able to stop and restart all of the server daemons and free up memory. Since then everything seems to be fine. In researching the cause, I find that my kernel does not have high memory support compiled into it (the default). Now this is all a little over my head, so I'm asking here, what do you think, will recompiling the kernel to include high memory support resolve this? The machine had been up for 168 days before this happened. It has 1GB of physical RAM, and 2GB of swap space. Slackware 10.0. Thanks, --charlie -- Charles Farinella Appropriate Solutions, Inc.

If you have between 1GB and 4GB of RAM, then you want to set this to the 4GB option. > It has 1GB of physical RAM, and 2GB of swap space. Slackware 10.0. What kernel are you running?

One of our students in the NHTI LAMP class happened to mention this very book last week. I asked him about it, because of Randy's message, and he says he's been very pleased with both the book and with Mepis itself.

Mmmm, what reasons are there for upgrading to 2.6 at this point. I've thus far treated 2.6 as 'testing/unstable' kernel, and since many of it's nicer features (like SATA) are getting backported to the 2.4 series, I haven't had a reason to venture into 2.6 land yet. -- Seeya, Paul ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

I'll bite: drivers do not a kernel make. Many of the subsystems (eg., memory management, kernel locking) have been substantially refined, and I doubt that all the enhancements in, say, SATA are being backported. In addition to that, IMHO, the 2.6 kernel is, BY FAR, the most stable .0 (and subsequent) release I've ever seen. Gone are the days of the 2.4.9 debacle, the 2.2.0 debacle, etc. I've been running with nary a glitch since 2.5.58 (?) or so, and have upgraded all my important servers to 2.6 back at 2.6.3. I doubt it's 100% BugFree(tm), but I do think that, kind of in opposition to your stance, unless there's a reason to stick with 2.4 (such as, "It just works," which is a fine reason), 2.6 is the way to go. $.02, etc., -Ken ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

For me, it depends upon exactly which 2.6 version I'm using... I'm currently sticking with Fedora's 2.6.8-1.521 kernel, because the 2.6.9-X and 2.6.10-1.9_FC2 updates gave me problems with all of my USB devices. Specifically, when I connected an/or disconnected them, the kernel would frequently (but not always) oops, and the system would eventually stop working after that (not surprisingly). If I tried to shut down at any time after the oops, the kernel would invariably get wedged before the shutdown was complete. I think the 2.6.10-1.12 update was better, but I discovered that my (win)modem driver won't work with the 2.6.10+ kernel, so I haven't really had opportunity to test it extensively. -- Derek D.

Well, our product is based currently based on the 2.4 series, so there's significant resistance to moving towards 2.6 because of that. Also, we try to run the same kernel not only on the product, but also everywhere else; desktops, servers, etc. That way we have the widest possible use-case of the kernel. If there's a bug, we're using the kernel in so many different ways, that hopefully we'll find it before it turns up at a customer site. I didn't mean to imply *I'm* hesitant to upgrade, just that I haven't found an overly compelling need to do so. Keeping in mind that to propose shifting would also require me to convince all the various "powers that be" we shouldshift. That's sometimes a lot more effort than it's worth ;) -- Seeya, Paul pgpW8IaZcgC9D.pgp Description: PGP signature

I use 2.6 in a number of servers and workstations, and it's as stable as ever. I build them from the kernel.org releases. My problem is that some of the drivers I need aren't keeping up with the kernel releases, like the NVIDIA drivers, for instance. Still, if you are running mission critical, you have to make the best decision for your situation. There are issues with certain driver/kernel combinations, but usually there are workarounds. -Fred ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

The driver issue in 2.6 has impacted me, though in the other direction. 2.6 includes some new mouse drivers and I've had issues with those in oldish touchpad laptops (though more recent releases have been better).
