kernel paging problem

Post by Eric Villemonte de la Clergeri » Sat, 07 Aug 1999 04:00:00



I keep having 'kernel paging' problems on a laptop under Linux. In
most cases, kswapd becomes zombie and I have to reboot the machine.

The typical /var/log/message is
Aug  4 16:48:08 vagabond kernel: Unable to handle kernel paging request at virtual address d066da15
Aug  4 16:48:08 vagabond kernel: current->tss.cr3 = 00101000, pr3 = 00101000

kswapd is not the only process to suffer this problem. In all cases, I
get the same information about shrink_mmap+116/520,
try_to_free_page+81/184 and Code.

I am running Redhat 5.2 Linux 2.0.36-1 on a Dell CPi 366 XT with 128 Mo of RAM.

Any help or information will be most welcome !

Thanks,

maybe your ram is corrupt?

1. kernel page problem

Hi,

        We have matrox meteor framegrabber in my Linux box.  Sometimes, we get
the following message saying that the kernel can't handle a paging request
when we access the meteor,

maemb1:/home/users/wkfung>Unable to handle kernel paging request at virtual
add7
current->tss.cr3 = 02320000, %cr3 = 02320000

        What does the above indicate?  After this message popup, the program
seems to run fine.  How to fix the missing paging request?
