I don't think crach dump to net is much better than any other kind: a corrupt kernel can still corrupt your data.

You might try a watchdog timer (even a card) to help with your system problem. There are various drivers for them. And I guess a kernel dump could well help afterwards.

I strongly disagree. If the crashdump code doesn't even TRY to access your disk drives, it's not very likely to corrupt the filesystems thereon. Of course, the crash that lead to the invocation of the crashdump might already have done that, but you can't blame that on the crashdump code.
