Hi Ashwin,

for what it's worth, I have exactly the same problem on my Dell GX 
260/FreeBSD 5.3 RELEASE machine. When it panics, it says it's starting 
to write a dump, but doesn't continue. The disk lights remain off, so 
there's definitely no activity.
Strangely enough, when I use my Dual Tyan box (AMD-based) with a kernel 
compiled with the same config file, I get a dump without ahny problems.
I mentioned this on -hackers a few weeks ago.

Cheers,
Gerald
