While efax is running on another terminal

So no IRQ conflict for the 537 device. This also shows your processor is a single core.

Your /var/log/syslog gets flooded with such kind of messages:

Jan 5 14:40:39 ubuntu-11 kernel: [39585.162477] Inbound IN=eth0 OUT= MAC=00:11:11:ce:98:15:a4:ba:db:fb:8a:d1:08:00 SRC=10.10.5.100 DST=10.10.5.102 LEN=60 TOS=0x00 PREC=0x00 TTL=128 ID=11645 DF PROTO=TCP SPT=57892 DPT=445 WINDOW=8192 RES=0x00 SYN URGP=0

This adds work to the processor giving less time for wvdialconf and efax when they select with a timeout. Are you running Samba ??
