No mouse support for Indy in 2.5.75 ?

No mouse support for Indy in 2.5.75 ?

Hi.

I tried kernel version 2.5.75 on my Indy. It works fine with the
exception that the mouse in XFree86 does not move. The devices are 
available, but event debugging shows no mouse events at all. Are there
any special configuration options for the Indy mouse except the ones in
the 'input' section ? Dmesg output and kernel configuration are
attached.

Regards

Frank

We knew there was something wrong in that area; the probe for kbd and mouse
also takes very long on the Indy.  What worries me more are those
kernel messages from your log:

mount: Exception at [<88113a38>] (88113bf0)
mount: Exception at [<88113a38>] (88113bf0)
mount: Exception at [<88113a38>] (88113bf0)

Hm, seems to be easier to stay at 2.4.x for the moment. I'll have a look
when I find some time...

.... which means that this problem might well be an old one, because my standard
kernel is a 2.4.

Well, as for the PS/2 issues, you'll have to read through the code yourself,
nobody's digged into that so far.

The kernel messages otoh are not sign of a kernel but an application bug.
It seems mount did pass bad addresses to the kernel through some syscall;
these messages are the sign of the normal mechanism to intercept bad
address arguments to syscall kicking in.  You won't get those messages
anymore in 2.6 btw.  The kernel only print's them if the second digit of
the version number is odd, see development_version in arch/mips/mm/fault.c.

Hi Ralf.

Is there any additional information I can collect on these issues ?
