Follow-ups

--- Sonic Zhang                                              2010-03-30 02:04:29

It looks that fetching data from current_tx_ptr->next hits misalign

exception.

How to replicate this crash?

--- Robin Getz                                               2010-03-30 15:20:38

I was just doing lots of rsh/rcp traffic.

So I would assume it would happen on toolchain testing as well...

I only saw it once, so (today), I'm not sure it wasn't a bad userspace (which I

was doing) that corrupted some other memory...

If the toolchains tests are passing without crashing the kernel - I'll close

this.

Grace?

--- Robin Getz                                               2010-05-25 08:05:13

While doing this test - it could have been a bad application writing over kernel

memory...

Closing since no one can replicate.
