Hi,
   I upgraded from 2.6.13-15  to 2.6.17.1 and I can't see any UEVENT message  
generation. I am running udevmonitor and it is just blocking on receiving 
UEVENT from the kernel even after I insert a usb keyboard/ usb storage / usb 
bluetooth dongle. 
Attached text file is my kernel configuration.
I am running SUSE LINUX 10.0.
In the default Suse kernel (2.6.13-15)  configuration 
/proc/sys/kernel/hotplug is null and even then it seems to work fine and when 
I run udevmonitor it seems to get UEVENT messages.
Kindly let me know what I am missing.
