Try 2.4.20 as all the older kernels were easy to lock up by dosemu, which is now fixed. > Maestro 2E. And what about video? It was reported that xdos crashes X sometimes on some video boards.

Try ALSA drivers with OSS emulation. Maybe it is just an ESS OSS driver buggy and the current dosemu sound code is extremely evil to the underlaying drivers and exposes all of their hidden bugs. It locks up the Aureal drivers on my machine after some minutes of playing, but as that drivers are proprietary, this can't be fixed. Another usefull test would be to try dosemu with a pc-speaker OSS driver. If the problem goes away by this, then it is definitely a problem of your OSS driver. Because even if the dosemu sound code is buggy, this doesn't excuse a kernel lock-ups.
