Linux creator Linus Torvalds released 2.6.0-test8. He listed the most noticeable changes as fixes for: the ‘/proc/PID/stat’ oops, the Athlong prefetch bug causing occasional spurious page faults, serverworks PIO autotuning, cpufreguency calculations and NFS O_DIRECT.

how many cpus can 2.6 kernel support? if the kernel support 8 cpus,can it support 8 p4 cpus with hyper-threading?
P4s dont support smp at all, you have to use Xeon’s for that.
Ok, and what about having 8 Xeons with ht enabled?
The 2.6 kernel doesn’t have some hard limit, say 8, to the number of supported processors. It’s just that as you increase the processors beyond a certain limit you get diminishing returns. 8-way systems with hyperthreading (using Xeons) are IMO still below this limit, and not that uncommon anymore. So, yes, it will support it, quite well in fact.
O yea, 2.4 will do that. Easy.
P4s dont support smp at all, you have to use Xeon’s for that.
Yeah, that why Athlon MP are so popular in my Country for SMP. I have a dual PIII 1 Ghz but would not pay for XZeons instead of dual Athlon (This *are* relayable).
[preamble]
usepackage{on topic}
I will not upgrade my actual Mandrake 9.1 until there is no 2.6 Linux Kernel based distro as common place.
There is the new 5.1 FreeBSD kernel out there to try too.
this thing doesn’t standard input -stdin- properly the backslash characther … weird.
There’s no hard limit to the number of CPUs you can run Linux on. There is however a hardware limit of about 12 CPUs on the x86 architecture. Anything more and it would become too complicated giving you little or no benefit at all. Do some reading about SMP if you wish. One of the main bottlenecks is cache-snooping — making sure that any one CPU has the latest piece of data. If you want to go beyond 4 CPUs, you’ll be better off setting up a Beowulf cluster.

Well, if you want to go beyond 8 ways, you wouldn’t use SMP, instead you would look at something like NUMA or what ever UNISYS uses for their 32way Xeon box.
Just today up upgraded to 2.6.-test7 and now there’s 8. BaHumbug!

are you talking about how the terminal will not accept “” as part of the path name?
heh…ummm….Unix is not DOS. you need to use “/”
IMHO DOS always did it backwards. “/” is a much nicer easier to type character

Pretty cool, i just noticed it has CryptoAPI. Therefore, time to test it:)
Try 2 times a backslash, like \\
> “/” is a much nicer easier to type character
yes, on english keyboards! on german ones you have to type Ctrl+7 for ‘/’ and AltGr+ß (um, well, ß is 2 keys left from backspace) for ”.
That’s because there are more letters in german (ä, ö, ü and ß) and so almost all special signs are only reachable by key combinations and so / and is both not that easy/fast to type.
well that just plain sucks. someone should redesign the keyboard for better ergonomics.
use english keyboard: “/” is reachable with your right pinky.
btw. using backslash as path-seperator is one of the most stupid things Billy could do… if you wrote some lines in C/C++, Java, PHP or JavaScript you’d know what I’m talking about

That’s probaly Windows market share is as low as it is.
Does anyone know what ‘input in flex scanner failed’ message means ?
I just moved to 2.6-test8 today and I’m now getting that in dmesg logs.
A google shows it as old bug in php, however I have the latest version installed and the bug is only apparent when using serverside include(); in php websites.
‘input in flex scanner failed’ message means ?
This might seem starnge but Flex lm is a licensing app for other commercial app seerved on a network environment. Some commercial apps on Linux use Flex lm like the Intel C/Fortran compiler and Maya 3D.
Maybe the new kernel 2.6 has a scanning function with a php file ?? (doubt it) to search for licenses that yopu don’t have.
It might be another thing, completely diferent of Flex LM (LM = licensing manager).

Same here ! my POS style (very small) keyboad sometimes loses it under X keymap.
Flex is a lexical analyzer, and has nothing to do with licensing.
James,
But, P3s supported SMP, as did P1s & P2s I believe.
