FWIW, this also affects PPP over an async serial line (in my case to a
56Kb modem). During cdparanoia runs, the modem Tx/Rx lights all but
stop as the missed packets drop retransmissions into the minute+
timeframe. (Oddly, I don't recall seeing framing errors from ifconfig;
must be the lower level ppp substrate or some such...)
I can confirm this with 2.4.20, am mostly certain it affects 2.4.21
(will have to retest to be sure). Similarly to Dave, I'm using an
IDE/ATAPI burner with both DMA and UNMASKIRQ enabled.
