As Rich alluded to, it's a bit of a lottery.

I have two identical P4 2.4 boxes with Intel 845 chipsets running 
updated, stripped down Redhat 7.3 and custom compiled kernels containing 
nothing more than is required for asterisk in a headless, ssh access 
only situation. All onboard sound, USB etc. is disabled in the BIOS.

One box has 3 x TDM400P - 2 x FXO and 8 x FXS (latest rev) all on 
individual IRQs. Until a couple of months ago it had 2 x X100P and 8 x 
TDM400 FXS and required driver reloads about every couple of months over 
a 1 year period. I replaced the 2 X100s with the TDM FXOs for a few 
reasons including a hoped for improvement in reliability.

In the 2 months since, I have had to reload the drivers once - the logs 
showed 4 error mesages, "Ouch, part reset, restoring reality" for each 
of the ports on one of the FXS cards.

The second box has a single TDM with 4 x FXO which is IAX2 trunked to 
the first. It originally had 2 x X100Ps and gave no problems at all for 
a year. In the 2 months since replacing with the single TDM, the drivers 
have needed reloading once, with no sign of any errors in logs.

Apart from the above, I have been very happy the system and have had no 
echo problems.

Richard
