swapping problem on kernel >= 2.4.14

swapping problem on kernel >= 2.4.14

[Caleb Moore]

I have tried to change to kernel 2.4.16 from 2.4.13 and my system crashes 
every time it starts using swap. This is the case down to 2.4.14 even when 
it is built using default options. My system is a AMD duron with 128MB of 
RAM and two swap partitions both 128MB on my non boot hard drive.

could someone please fix this

thanks

You can significantly raise probability of this being fixed with some
investigation: does it crash with one swap partition? without swap partitions?
with swap file? does it produce an oops? etc

Ok I checked my system with one swap partition, no swap partitions and a 
swap file. One partition resulted in a crash but after a longer duration 
(two or three times as long. I cannot understand this). A swap file acted 
in a similar way to the single swap. After removing all swap the system 
was as stable as linux is rightly reputed to be.

The kernel does produce an oops when i crash it but for some reason the 
screen blacks out a few minutes later and i am unnable to finish recording 
the sym-debug stuff and cannot get useful information from it. It is not 
logged by klogd and I don't get much further then the registers. The 
message It gives me is unnable to handle kernel paging request at virtual 
address 00015e00 although of course this adress changes.

Is there anything else I can do?

Sorry, but this info is not enough. Guys most likely won't be able to
fix this if they don't know where your kernel crashed, CPU registers at the 
crash time etc.

Screen blanking: some power-saving? Try to disable.
Maybe you can photograph it if it turns off by itself too fast? :-)
