System: NetBSD copenhagen.cs.mu.OZ.AU 1.3H NetBSD 1.3H (CompSci-IPX) #4: Mon Sep 7 03:44:40 EST 1998 firstname.lastname@example.org.OZ.AU:/local/netbsd/src/sys/arch/sparc/compile/CompSci-IPX sparc
Continuing from a breakpoint (or other halt) on a kgdb client
sparc causes almost immediate panic - seemingly caused by a
register (or registers) not being properly saved/restored
during the kgdb exchange with the controlling system.
Simply setup and run kgdb on a sparc (4c if it matters, IPX), cause
the controller to connect to the target (which stops the target),
tell the target to continue - observe panic. Happens reliably when
the target was otherwise just sitting in its idle loop.
Don't use kgdb on sparc.
Note - this is a very late report of a problem observed (it seems
from the date of the kernel that is running) more than 2 years ago.
I don't recall seeing any change notifications with comments that
would suggest this has been fixed - but 2 years is a long time.
