Re: Wine + serial port basically hangs system

Ok, I guess that you only pasted the first lines.

Yep.

What is a little
confusing is your high load. Not only do wineserver and Heavy Weather
eat up all of the CPU, there also are some 20 other apps competing for
it. Either the first two are hogging the CPU so much that everything else
has to wait,

Yep. Nothing else of consequence is running on the machine, it's basically idle.


What is the output of 'setserial -a /dev/ttyS0'?

(with HeavyWeather running)

 setserial -a /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test auto_irq


Later last night, I discovered that if I launch the app with a 'nice' level of 19, the rest of the machine at least stays running. The app itself is a little sluggish, but it mostly works.

The load average ends up looking like this when I have it set to the lowest priority (again, the machine would be basically idle, if it weren't for this weather app.

Its very possible that this app could just be very poorly written... I haven't been real impressed with it. But if there is anything else I can do to make it run better, that would be great.

Thanks,

Dan
