The release notes say to modify file sys/data/qd_data.c so that the variable DMA_BUFSIZE is defined as 10. I made this change (from an original value of 1024 * 3) and rebuilt the kernel,which does not boot. It should be 1024 * 10 Donna Converse MIT X Consortium

I am having a problem getting the x11r3 Xqdss up on my VAXstation II/GPX running Ultrix v2.3. I tested it on the unmodified kernel and it sort of works, except the system eventually hangs. The release notes say to modify file sys/data/qd_data.c so that the variable DMA_BUFSIZE is defined as 10.

Which release notes are you referring to? Ultrix 2.2, 2.3 or X11.3? I have not seen the note in question, and am interested. Someone at DEC mailed me a new qd.o to fix the problem with the server reset hanging the workstation, but this change is new to me. I will try the 10K buffer to see if it changes anything.
