Mouse detected in bios but not assigned IRQ in /proc/interrupts
 

Hi there,

I am having a problem getting my mouse to work.

The bios detects the ps/2 mouse correctly. It should assign the mouse to IRQ 12, however when I list my /proc/interrupts there is nothing assigned to 12?

- IRQ 12 is not reserved in bios.
- There are no IRQ conflicts that could cause the problem

What else could be going wrong that I can look at to fix this problem?

This problem is stopping my embedded peewee linux X windows from booting into X. (I initially was checking that XFree86Config was set correctly and looking at /dev/mouse /dev/psaux mappings, but they are all fine....).

Any help would be appreciated!
Thanks in advance,

go into your bios and make sure the option (assign irq to usb) is enabled, that is if you have usb mouse.

No, its a ps/2 mouse

well i think it may be a problem with the kernel I am using and my hardware ?

I use the 2.2.17 kernel. Are there any known issues with IRQ assignment with this build ?

I am still wondering if anything else can cause linux to not assign an IRQ to the mouse / not detect the mouse when it is detected in BIOS fine ?

Building a new kernel seems a little long winded, especially that it may not solve the problem! However I have used redhat 7.3 on the target system and the mouse works fine.

/me bangs head :)

whoa, that kernel is before my time (I started with 2.4.6 when 2.4 wasrather new) you may want to update keernels.
