Well, after you did this, did you check for new firmware packages for debian also. 
These might be out of sync. 

dpkg -l |grep firmware
I dont know if linux is also loading firmware, but check that, should be somewhere in the bootlog/dmesg output. 
If thats the case, i would look in : packages.debian.org if the current firmware is available in newer packages.

I dont think its required. 

I would start here with newer kernel and linux firmwares. 

And possible the "specific firmwares" 
( like i use : firmware-bnx2 ) 

Cant help much beside above, i hope i gave you some ideas where to look at.
