[comp.sys.sun] SunOS 4.1 kernel read fault panics

km@mathcs.emory.edu (06/01/90)

We've been getting kernel read fault panics on our 4/280 server every few
days since we converted to 4.1. "crash" doesn't show a real pattern, since
we started saving the cores.  One time it was in the "ie" driver
interrupting a user program, another time it was in the "zs" driver
interrupting a system call.

We weren't seeing this in 4.0.3. The 4.1 is unpatched, the 4.0.3 had
various patches (at least some flavor of alm patches).

Anyone else seeing this?

On our 3/280 running an unpatched version of 4.1 we're seeing daily parity
errors on zs1, the keyboard/mouse interface. The interesting thing is that
since we're using a terminal as a console this device is not included in
the kernel configuration file. It'd be nice to know what's going on.
