kernel crash on zfs send/receive on the same machine

[mailinglists35]

ubuntu 3.2.0-34-generic, zfs 0.6.0.88-0ubuntu1~precise1
this screen is all I could get from the machine

at the time of crash, I was transferring the zfs filesystem from one pool to another, as mentioned in #97.
the exact command was:
zfs send -v -R oldpool/oldfs@latest_snapshot | zfs receive -F -d newpool
both sending and receving fs had compression on

I can live with spl crashes, but I'm afraid of entire kernel crashes. What can I do to collect necessary debugging dump next time?

@mailinglists35 Unfortunately we're going to need a full stack trace to run it down either from dmesg or a serial console.

@mailinglists35 If it occurs again please grab the output from dmesg if the machine is still responsive. But for now I'm going to close this issue since there's not enough information to do something with. Also please open up new issues in the ZFS tracker and not the SPL tracker unless your sure it's an issue with the SPL.
