I have noticed that whenever I have disk access, my modem stops 
sending/receiving data for the duration of the access, and for about 1 
second afterwards.  Naturally, this shoots my FTP and HTTP throughput to 
pot, as well as disrupting interactive sessions, so I would like to 
alleviate the problem if possible.

My setup: A500 w/GVP A530 (50MHz 030 + 8M 32 bit memory), serial port at 
38.4k with CTS/RTS handshaking, -current kernel (from early May sources).

I know that some people with GVP controllers have terrible problems with 
disk access and serial port performance, but at least when I am running 
AmigaDos, I can be downloading at 1600 cps while I am accessing the hard 
drive.  In fact, I rarely have serial errors related to disk access.

Does anyone know what is causing this problem, and more importantly, if 
there is any easy way to fix it?
