Since updating my 2 TDM400P's, with 4 channels each, to REV E/F, I have 
seen very intermittant loss of dialtone on some channels, one hard 
lookup that required a power reset and a "Power alarm on module 1, 
resetting!", which oddly occurred in the small hours of the morning, 
when the phone was not being used, over a +_ 2 month period, where the 
first card has had regular daily office use and the second card 
virtually none.

The machine is a 2.4GHz P4 on an ASUS Intel chipset MB, running a 
stripped down Redhat 7.3 with a custom kernel compiled completely with 
asterisk requirements only. Everything not required for asterisk (USB, 
serial, parallel, mouse) has been disabled in the BIOS and there is no X 
or framebuffer installed. Two X101Ps are also in use.

I would be interested in hearing from anyone else running 2 x X101 and 2 
x TDM400 4 channels, who is having no problems at all.
