Package: linux-image-2.6.18-4-sparc64
Version: 2.6.18.dfsg.1-12etch2
Severity: important


Using a terminal emulator such as gtkterm or cu with either /dev/ttyS0 or
/dev/ttyS1 on an Ultra-10 an incoming break condition (pins 2-3 wired
together or RD touched to an active DTR) oopses the kernel reliably if
the console is controlled by the Sun keyboard.

This appears to not happen on an Ultra-1 (i.e. an SBus rather than PCI system)
or if the Sun keyboard is disconnected with the console on ttyS1. This latter
point makes it very difficult to get the text of the oops.

I believe I first saw this trying to set up the nut UPS monitor which I've
had working on older hardware and kernels.

Mark tested in off-bug communication that this bug is fixed in
2.6.26.
