For the record, I have tried this, and I still get lockups.
No changes. Sorry. :)
My machine does not seem to lock up as often as David Champion's, but then
again, I might have more memory (12MB) and thus might end up swapping
less. The lockups occur during fairly heavy disk activity, such as
when emacs autosaves a large file, or when the system starts to swap
a lot (this happens with you run X11, emacs, etc.. :) ). Worse yet,
my attempts to force this behavior to happen have failed (I hoped
that some useful messages might be printed to the console just before
the system locks up, but it always seems to happen when I don't have
my xconsole window up. Murphy strikes again.)
Again, my setup is:
GVP G-Force 68040/SCSI, with 12MB 32-bit RAM
Seagate ST31200N SCSI-2 drive (1 gig)
Quantum PD015S SCSI-1 drive (100 meg)
GVP I/O Extender
A2024 monitor (though I doubt this is relevant :) )
I am using a kernel compiled from current sources, but I have tried kernels
back to the July 9th binary dist. I have tried both with sync
enabled and disabled; the same behavior occurs for both.
