Package: linux-image-2.6.18-3-sparc64
Version: 2.6.18-8
Severity: critical
Tags: patch
Justification: breaks unrelated software
Hi,
at first: if the severity may seem inflated feel free to adjust it.
Well start with the easy things: my hardware is an old Sun Ultra 5. I
added an USB 2.0 controller because I do not have a type 6 mouse, only a
keyboard (output of lspci concerning the controller):
02:03.0 USB Controller: NEC Corporation USB (rev 41)
02:03.1 USB Controller: NEC Corporation USB (rev 41)
02:03.2 USB Controller: NEC Corporation USB 2.0 (rev 02)
The mouse works but at boot I get this:

According to http://lkml.org/lkml/2006/9/22/326

Well, I do not have any USB mass media which is dispensible and as this
may (or may not) kill data I opted not to try.
A patch is included in http://lkml.org/lkml/2006/9/23/184:

I compiled a kernel with this patch (wrecked a harddisk while doing
this, but this is almost 100% certainly not related) and the messages
disappears.
But as I tried to use sshfs to access another computer on my net this
happened:

The mountpoint is unusable (but luckily unmountable via fusermount -u).
I guess the same problem as above applies BUT I DO NOT HAVE ANY KERNEL
EXPERTISE WHATSOEVER!
If there is anything I can do to help please let me know!
