dd fills up kern.log, syslog and messages

The kern.tar.bz2 is over 5Mb, so I do not know where to store it. I had to delete other files (syslog and messages).

OK, it happened several times again. Here the content of kernel.log:

Apr 25 11:28:50 localhost kernel: [57665.880000] ACPI Warning (utdelete-0397): Large Reference Count (662C) in object e584dc7c [20060707]

Apr 25 11:28:50 localhost kernel: [57665.880000] ACPI Warning (utdelete-0397

And so on and so forth for 133Mb.

This is a messages file:

and last but not the least syslog

Thank you for your bug report. Please specify the version of the coreutils package you are using, and your current kernel version. Also: could you provide some more detail as to the use to which you are putting dd, and what filesystem types are involved?

version 5.97-5.2ubuntu3.
I did not use dd at all, but is always running:
~$ ps -A | grep dd
 3551 ? 00:00:00 pccardd
 4474 ? 00:00:00 dd
 4521 ? 00:00:00 hald-addon-keyb

 4525 ? 00:00:00 hald-addon-cpuf
 4526 ? 00:00:00 hald-addon-acpi
 4527 ? 00:00:00 hald-addon-keyb
 4538 ? 00:00:00 hald-addon-stor
I've got ext3.

Got it again. I have no idea what triggered it. Here are extracts from log files:

I guess this is probably the culprit.

fox123: do you get the same result? If you find other instances, a pstree(1) printout might be helpful, too.

FWIW I'm not seeing anything like this, also I'm curious as to how you connected dd(1) to these errors in the first place.

... Actually if that is the explanation then I guess dd(1) is actually only the messenger, and those messages are coming from the kernel?

I have upgraded to Gutsy and have not gt this bug so far. I will add a comment if it happens to me again.

This happens to me too. I am not sure if dd really is the problem or indeed just the messenger, but it does appear suddenly right before the problem occurs, while also using a lot of cpu (1 of 2 cores is totally busy which is almost never the case on this machine). my computer just freezes when the root partition is filled up on those log files and that's really anoying as you might geuss

im running intrepid (2.6.27-9-generic, also happens with i think it is 2.6.27-7-generic). my geuss is that something is wrong with the wireless driver (iwlagn), just because dmesg also complains a lot about that, certainly in combination with vmware 2.0, which it tries to link for nat networking, but this could be a sepperate problem

a lot of stuff going wrong, any idea where to start?

If you upgrade to Jaunty and still get this, try a 2.6.30 kernel and see if that helps.
