Running the latest kernel has caused some problems for me since 2.6.4 up to the current 2.6.5. I recompiled all interim releases and made a little report of the troubles I run into. All kernels are compiled with gcc version 2.95.3 20010315 (release).
2.6.4 -> everything ok 2.6.5-rc1 -> sensors broke (ERROR: Can't get <sensor> data!) 2.6.5-rc2 -> USB broke (kernel NULL pointer dereference in khubd) 2.6.5-rc3 -> networking broke (real weird stuff) 2.6.5-final -> networking fixed again!
I am real glad that networking was fixed again, but this still leaves me with the broken sensors and a non-functional USB Modem. This all happens on a Asus-MEW main board with a Intel Celeron (Mendocino).
The sensor module I use are w83781d and i2c_i801 and sensor reports in the first 2 lines
as99127f-i2c-0-2d Adapter: SMBus I801 adapter at e800
Since 2.6.5-rc1 sensors reports "Can't get data!" for all sensors while all modules are loaded normally.
For USB (already reported earlier on lkml) I get these message on startup with 2.6.4:

I am happy to supply more information or do tests if needed.
