I have noticed that with a Linux-based Netgear DG834G (DSL modem)
frequent pauses (example[1]) between external systems and 7-STABLE
(March 14th).  At first, I thought it was ipfilter or ipnat, but I took
those out of the picture by activating telnet on the router and
connecting directly to it.  Even running "ls /usr/sbin" on the router
would pause occasionally.  I did not (or did not recall) have these
problems with 6-STABLE (post 6.2).  I switched out the NIC (FA-311 (sis)
to a FA-310 (dc)), cable and tried different ports on the modem by which
to connect.  I also tried disabling all RFC sysctl's and SACK.  Nothing
helped.

Finally, I brought out an old DSL modem (SpeedStream 5660).  This fixed
the issue.  I think this maybe a specific issue between Linux
(2.4.17_mvl21-malta-mips_fp_le) and FreeBSD 7.  Is there anything else I
may test to see what is happening?
