We have been plagued with this kernel crash from time to time after
we upgraded our 400 machine from 2.01.01 to 3.00.01.

The full message printed on the console is:
OS: HALT: Modified Page Removal Failed
TO FIX: See System Message Manual.   OS-17508

Then the kernel stops, and the machine must be rebooted.  Pretty annoying.

I don't have this 'System Message Manual', what does it say?
Is this a known problem, perhaps I simply can order a patch?

Oh, and by the way:  The machine has 4Mb of physical memory.
MAXUMEM is set to 4096 in the kernel configuration, the crash seems to
happen when we have processes running with a virtual size of a couple
of megabytes.
