double fault on fresh CURRENT

[Andrey V. Elsukov]

Hi!

I have a "double fault" panic on the fresh CURRENT
when i try copying a several files to server via NFS.

Currently i don't have possibility for obtaining a
trace via serial console.

DDB trace seems like this:

Tracing pid 21 tid 100023 ...
kdb_enter ...
panic(....
dblfault_handler() ...
--- trap 0x17, ... ---
uma_zfree_args()
m_freem()
nve_ospackettx()
UpdateTransmitDescRingData()

pid 21 is an [irq5: nvidia0 nve0]

I can provide more info if needed.
