Bug report for MV643XX driver

Bug report for MV643XX driver

[Stuart Peloquin]

Kernel oops during heavy load downloads with the MV643XX driver on a PegII.  
I've replicated the problem on 2.6.17_gentoo-4, vanilla 2.6.17.1, vanilla 
2.6.18_rc3.  When downloading a large file from any fast mirror (I tested 
getting around 2.0MB/s) the system crashes after a random amount of time.  
Usually after 30seconds to a couple of minutes.

I took pictures of the call trace, I'm sorry about the quality, they were 
taken with a phone camera.  They can be viewed at

Thanks,
-Stuart

Thanks for the report Stuart.  I'm investigating this now.  Would you
mind sending me the config file used to build the kernel?  Also, which
version of gcc are you using?

Thanks,

Hi Dale,

Thank you for responding quickly.

This is with gcc 4.1.1 and the config file has been added to the web  
directory at http://web.mit.edu/peloquin/marvell/

Please let me know if I can provide anything else.
Thanks,
-Stuart

Can you test with an earlier version of the toolchain?  Maybe gcc-3.3?

Just this week I rebuilt a kernel for one of my Debian x86 server boxes
with gcc-4.1, and the tulip driver died early on.  When I rebuilt with
gcc-3.3, all was well.  I haven't had time to look for the details yet.

I'm not saying that gcc-4.1 is buggy, but this will help us narrow it
down.

BTW, I'm up against a deadline on another project, so I won't be able
to devote a lot of time to this today.

Thanks,
-Dale

Time is not an issue, I'm filing this after some drawn out testing.   
It won't be right away that I get it built under 3.3 either.

Thanks again,
-Stuart
