kswapd (?!) error

kswapd (?!) error

[Petre Bandac]

can anyone translate in plain english the error below, please ? (the computer 
was frozen, and though it responded to ping, none of the services running - 
sshd, ftpd and apache - worked)

thanks,

No to translate it properly into English you would have to do that yourself 
because your system has the details to decode the kernel oops below.
Help on that is written in /usr/src/linux/README, the part called;
IF SOMETHING GOES WRONG:  

Now lets see if i can take a guess at what you are doing, considering you 
give is no further information on what you are doing then all one can do is 
guess.

Possably you have compiled a new kernel and or a experimental kernel series, 
ie; 2.5.x, you may have upgraded some or other utillity which is uncompatable 
with your kernel version.

Or had your machine been running for a very long time,? do you have a swap 
space, how many programs were you using at the time of the crash, what 
processes were running, what was the last thing you did before the crash?

All and any info is better than the zero info you gave.

It could also be that you have a rouge program/daemon running which is doing 
things that kswapd did not like. kswapd is mentioned in the oops, however 
that does not mean kswapd caused the problem, kswapd is the daemon that died, 
looks that way to me.

Help us to help you, o BTW, if this happened with a 2.5.xx kernel then send 
your "detailed" message to the applicable "MAINTAINER" stated in the 
MAINTAINERS list in the kernel source and not here, experimental kernels 
should not be used by newbies unless they know what they are doing.

NOTE, i used the word newbie as a general term to reflect to this list of 
which you are a list-member.

Re: kswapd (?!) error

[Petre Bandac]

petre@k:~$ uname -a
Linux k 2.4.18-HTB #4 Wed Sep 25 02:47:50 EEST 2002 i686 unknown

it is a Slackware 8.1 installed a few weeks ago

I have 256 MB RAM and 200 MB swap space

I stay away for the experimental kernels, as what I want from my system is 
stability.

the uptime of the machine was at that time 4 days, 21:14:36. It is my home 
box, I run x-window on it (KDE), but at that time x-window wasn't running, so 
the only processes runing were those required by the system, plus apache plus 
http (below I'll list them). The only reason which comes to my mind is that 
at the time the crash occured I was doing a ftp upload on the machine @ ~200 
KB (yes, kilo Bytes). If it makes any difference, I'm connected through a 
LanCity cable modem.

I shall look at the file you mentioned, richard, thank you, though I would 
like to have some opinions on what caused this error (one of the few "fatal" 
errors I have seen on linux machines yet).

Then may i suggest trying the data transfer again, with of course the same 
things running as you have shown with ps below.

I suggest you read the whole piece about solving problems as there are 
several things you can do first before you go reading about ksymoops.

Re: kswapd (?!) error

"More information
   on making sense of the dump is in Documentation/oops-tracing.txt"

and

"You can use the "ksymoops" program to make sense of the dump."

seems like I've got some researching to do today :-)

thank you, richard, for pointing the direction,

Re: kswapd (?!) error

[Ray Olszewski]

OK. You want an opinion. It's only a guess, but I'd suspect a problem with 
your swap partition, since the failure described is a paging problem:

         > > Oct  5 04:45:04 k kernel: Unable to handle kernel paging 
request at
         > > virtual address 361dcf1b

Also, ftp transfers tend to fill up memory. With 256 MB of real RAM, and 
the process list you sent, an ftp transfer mat be the only thing that ever 
triggers use of swap space.

To explore this guess, try the following (assuming this is a problem that 
recurs):

         1. Run "top" in some way that will let you see its last output 
before a failure (maybe over a telnet or ssh connection). Then notice if 
this problem occurs when you are just starting to use swap.

         2. Disable your swap partition and see if the problem stops happening.

         3. If you do NOT have DMA enabled for your hard drive, try 
enabling it (with hdparm) and see if that helps. The problem may just be 
timing.

All this said, my guess is only that -- a guess. As I noted in another 
recent thread, a large ftp transfer is a good stress test for all parts of 
the system, so it will unearth any hardware problems you might have (in my 
case, most recently it unearthed a marginal power supply, as an example -- 
different failure mode, though).

I'll try another ftp transfer - see if things happen the same

Console fonts and colors

[Brett]

I use SuSE 8.0 and mostly use the KDE UI but find myself more and more
using the standard text console either by doing a Alt+f2 or not even
starting X at all.
What I would like to do is change the color of the font and maybe the font
it self.
Is this a hard thing?   If it involves setting up a fonts server or such,
maybe I'll make do with what I have. It's not all that bad really.   My
goal was to change the font color to green and maybe find a font that I
could get a few more words on a line.
Thanks,

Brett

 I don't know about colours (I quite like white on black), but the way
to change the font is to use either `consolechars' or `setfont',
depending on whether your distro ships console-tools or kbdutils.
Unfortunately, all this will really do is change which characters map to
which ascii codes, for example for me ¤ maps as a euro symbol using
latin-{0,9}. Your distro probably sets a font already, in Mandrake they
use `setsysfont' which is a wrapper script.

 Now, if you want more characters on a line you either need SVGATextMode
(never tried it, it's just an application) or a framebuffer. I use
framebuffers, you have to recompile the kernel for your particular
video card (or vesa will I suppose work) and then give the right
options to grub or lilo. For lilo I use

video=matrox:vesa:0x117 # matrox, e.g. mystigue, 1024x768
video=atyfb:1024x768    # old ati card, 1024x768

I've also used the following from an old Mandrake install -
video=vga:791           # vesa, I think this was maybe 800x600

 This is documented to varying degrees in the kernel source.

No, only it is hard to understand the doco.  You can mess with the
colors using "setterm -foreground green -background white" for instance.
load a font with "consolechars -f fontfile".
"ls --color=yes" will reset the console attributes when it exits,
though, so you might want to alias that to a wrapper script that resets
the attributes to what you want.  I don't know of a way to _read_ the
console attributes, which is probably why "ls" does the way it does.

look in /usr/lib/kbd/consolefonts to see what fonts you have lying
around.

There are some other funky ones lying around on metalab.unc.edu
(www.ibiblio.org/pub/Linux) somewhere, I think.

Easier to get a few more lines on a screen.
