Comment to ITMX F3 GAS signals became glitchy from yesterday (19212)
[Ushiba, YamaT]

For investigating GND issue around IXV racks, we prepared a new AA chassis (JGW-S2213729)
Some jumper pins were removed in order to avoid local GND loops.
We will try to replace AA chassis and check the state of F3 GAS glitches tomorrow.

JP1, JP2 (both 1-2 and 3-4), JP3 and JP6 (both 1-2 and 3-4) were removed for all 32 channels.
