[-- Attachment #1 --] I mailed a simple way to reproduce the serious brokeness of the serial port driver on my system and no one responds. What does this mean ? Does core know that sio is seriously broken and doesn't want to admit it ? [dont take that comment too seriously please]. What am I supposed to think ? Here we go again..... Can someone please run M.A.M.E. (/usr/ports/emulators/xmame) and then exit from it and then try to use user mode ppp. [NOTE you will need a M.A.M.E. ROM image from somewhere]. On my system and the previous system I had, this results in serious amounts of silo overflows, so much that the serial port is useless which requires me to reboot before I can use user mode ppp properly. My user mode ppp is fine unless I run MAME at any time before using user mode ppp without a reboot inbetween. All I want is for others to try to reproduce this problem.

[-- Attachment #3 --] Re-nicing wont help as I have just confirmed that the problem occurs if I run MAME, exit MAME and then get on the net. Very wierd... after running MAME, the serial port is unusable for ppp unless I reboot. Just doing a DNS lookup causes several silo overflows. MAME does something very strange to the system. I will grep the MAME source code for anything related to serial ports.

Tryon from "Nature" Vol.246 Dec.14, 1973 [-- Attachment #4 --] This problem is easily reproducible. However to do so, you need a ROM image for an arcade game that the Multi Arcade Machine Emulator emulates as it wont do it without any roms in the directory "/usr/local/lib/mame/roms". I am using xmame installed from the ports collection (/usr/ports/emulators/xmame) on a very recent -CURRENT machine. If I run xmame *before* I get online with user mode ppp (or while I am on the net), the serial ports get hosed and I have to reboot or I continually get silo overflows. This is not right as it happens AFTER I exit xmame !!! Please can someone else reproduce this problem as I'd hate to think its only on the systems I have owned (Pentium 166 and Celeron 300). -- /=======================================================================\ | Work: Matthew.Thyer@dsto.defence.gov.au | Home: thyerm@camtech.net.au | \=======================================================================/ "If it is true that our Universe has a zero net value for all conserved quantities, then it may simply be a fluctuation of the vacuum of some larger space in which our Universe is imbedded.

Tryon from "Nature" Vol.246 Dec.14, 1973 [-- Attachment #5 --] My usermode ppp works fine normally as I can quite happily download 4 things at once without a single silo overflow (as I did last night) even when there is lots of disk activity or X11 activity. Note this problem is unrelated to newbus as it occurs both before and after those commits.
