[SLE] Slow FIFO's in 6.2

I use xcdroast's readcdda piped to sox to make it a wav file. I did
this under 6.0, 6.2 fine. Now runs verry slow... The actual readcdda
part is very fast( about 1 minute for a 5 minute song ) by itself(36x
cdrom), but when I pipe it to a fifo and have sox read the fifo and
convert it to a wav file, the readcdda part slows up greatly.... to 1x
speed it seems. Infact the whole sox conversion process is much slower
now. Does sox use fifos to do the conversion? Are slow fifos the
problem or is sox now slower? I've used this process in both 6.0 and
6.1 to rip and encode mp3's and this part of the process has always been
verry fast. Piping it to sox never slowed up the process like this.
Then to top it off the wavfile is incomplete and has premature EOF!
I've tried cdparanoia too but that gives me the following error:

SCSI transport error: timeout waiting to read packet

SCSI transport error: timeout waiting to write packet

Even recompiled cdparanoia from source rpm, same error...
Not really concerned about cdparanoia not working just want my fast
fifos back.

Any ideas what may have changed? SuSE6.2( duh ), Kernel 2.2.12, SCSI
emulation for my CD-ROM and CD-R.
