I have a program that uses gnuradio to work with a HiQSDR.
The first time I fired up qsdr it worked.
Closing it down and re-opening later I got the error. A reboot of the system
didn't solve it.

Sid,
What version of GNU Radio are you using for this? You should try to
pull in the filter from the filter module instead of from gr:
from gnuradio import filter
fir = filter.fir_filter_ccf(decim, taps)
....
Also, what is your processor?
Tom
This is the output from the openSUSE boxes and the CPU flags which don't
include sse4_a.
Later I'll try rebuilding gnuradio with "-msse3" to see if that helps.
