| |
Hi I am having serious problems with the vm in 2.4.10. Here is my bugrepport:
System configuration: Debian GNU/Linux 2.2 potato, bunks .deb files for kernel 2.4 gcc version 2.95.2 20000220 (Debian GNU/Linux) 600M swap
Hardware: AMD K6-2 400MHz (66*6) AOpen AP5T motherboard 160M SDRAM 580M swap
Tested kernel versions: 2.4.9 ok 2.4.10 crashes 2.4.10-ac4 ok 2.4.10-ac10 ok I also compiled 2.4.10 with only a minimum of options selected in my kernel config. No modules, no network, no k6 optimisations (used i386), nothing that isn't neccessary to start the system. But I still got the same problem with 2.4.10
Problem desciption (On 2.4.10): When I run a command that use up all the main memory my console immediately fills upp with lots of messages like this:
"__alloc_pages: 0-order allocation failed (gpf=0x1d2/0) from c01232ee" and then "VM: killing process X"
where X is any process that happens to be running, from bash to syslogd and even init. This kills all my processes in a couple of seconds. Then everything but my login is killed. But when I try to log in (even if I wait a long time) I immediately gets the errors. I cant reboot by ctrl+alt+del either since VM kills shutdown.. So I have to manually reboot the machine.
How to replicate the problem: When I tested the various kernels I made a 200M file with: "dd if=/dev/zero bs=10k of=/tmp/bigfile count=20k" And then ran "md5sum /tmp/bigfile" It works fine on 2.4.10 untill the main memory is full, then the problem occurs. The command executes fine on all the other tested kernels.
Acctually, this was how I discovered the problem. After having upgraded to 2.4.10 I was going to check the md5sum of a linux-mandrake .iso i downloaded for my brother. But thats of-topic ;)
