Bad news - crashed about an hour after I wrote this email - under

reset the adapter... then hw watchdog rebooted the system.
It's a pity. Anyway, I'd be still interested in CONFIG_PACKET_MMAP off
if you find time.

Ok - any particular patch set to try with? I'm going to start with a
clean tree using the latest 2.6.32 from git (tried 2.6.33-rc3, but
can't get a usable console... will look at that later.)
My "Berck E. Nash" and Stephen's "pskb_may_pull" sky2 patches. (BTW,
could you remind if it worked any better with 2.6.31 or earlier?)

I'm not sure my crash-and-burn runs yesterday included the pskb_may_pull patch :(

Going to rerun with these patches and with and without MMAP. Will also retry both with jumbo frames if possible.
