high cpu-usage after update firmware

[Андрей Грошев]

Hi,

I'm have 3com switch.

display device manuinfo 
Slot 1:
DEVICE_NAME          : 3CRS48G-24S-91
DEVICE_SERIAL_NUMBER : 9T3FA1MDB9A00
MAC_ADDRESS          : 001E-C1DB-9A00
MANUFACTURING_DATE   : 2009-05-11
VENDOR_NAME          : 3COM

 One fall, I downloaded the firmware version of 2210.
By the way, now cannot find it on the site HP, showing there are only versions with status: "Previous"

Yesterday got his hands to upgrade the firmware.
And now I have problems due to high CPU load.

Today found out that loads the CPU - lldp.
How to find out exactly what to LLDP wrong?
