Subject: "Can't handle paging request" , 99p7-8


                                           Norderstedt, 25.04.93

 I have the following problem:

  This appens with kernel 0.99pl7, 0.99pl7a, 0.99pl8 and 0.99pl8a.

  A few minutes after i boot up and start memory intensive programs (like
  mke2fs[the old version] or gcc) my system hangs with one of these errormessages:

   1. Can't handle kernel paging request at C....
      Swapper killed.
      Panic: System halted.

   2. General protection fault.
   3. The system simply hangs w/o any message.

  I know this isn't precise but i don't want risk my system in re-
  producing the messages.. sorry...

 Now comes the thing that baffles me: if i turn off the cache in the setup,
 all works allright. I hadn't had any errors since then.

 I suspected a hardware problem, so i ran a few test programs: memory and all
 the rest tests allright; but a program that tries to figure out the cache size
 and cache organisation states that the dirty tag ram isn't ok.(i looked
 at the board, the dirty tag is really there).

 What do you think, is it a hardware or a software problem?

 My configuration:

  386-40-128 (opti-chipset)
  8mb of ram
  Adaptec 1542C
  Quantum LPS240S
