Searching google for 
	"Acer TravelMate 200" irqpoll
yields this bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333831

which is also in the kernel bugzilla
http://bugzilla.kernel.org/show_bug.cgi?id=5938

A couple of comments seem interesting:

'Combination of "irqpoll pci=routeirq" seems to resolve the reboot whilst
 playing a CD, although the stack dump during boot remains.'

and right at the end:

'Despite discussions with upstream, which suggested this issue might have
 been fixed in 2.6.18, the 2.6.18-4 kernel in the Debian-Installer
 tickles this problem on the Acer Travelmate 200DX.

 Simplest workaround is to boot with the kernel option "acpi=off".'

If I recall correctly, Edgy is using 2.6.17.  Perhaps you might try with
the latest beta of feisty (which is 2.6.20).  If it doesn't work straight
off, add 

	acpi=off

and see how you get on.
