Unresolved Symbol: best_copy_to_user (Examined/Solved - lm_sensors-2.5.4, Linux2.2.14-5.0smp, RedHat 6.2)

[contact]

Problem in detail:

I get the same problem as described in ticket #359. I have tried compiling

as kernel patch or separate module. Does this happen to SMP only????

[root@dcftt /root]# modprobe i2c-elv

/lib/modules/2.2.14-5.0smp/misc/i2c-core.o: unresolved symbol best_copy_to_user

/lib/modules/2.2.14-5.0smp/misc/i2c-core.o: insmod

/lib/modules/2.2.14-5.0smp/misc/i2c-core.o failed

/lib/modules/2.2.14-5.0smp/misc/i2c-core.o: unresolved symbol best_copy_to_user

--- thanks for the report.

Ticket 359 was never resolved and I don't have any

record of any followup.

I've asked our group for ideas.

Follow up by sending mail to sensors@…

I can't find the symbol best_copy_to_user in the kernel tree. Are you sure you

are running a vanilla kernel without any additional patches? If you did get your

kernel from a distribution CD, you can be almost sure it is not vanilla. As we

can't support patched kernels (sorry, it is just too much work), you are on your

own unless you get a 'normal' kernel.

Good luck,

Frodo

Hi, Frodo:

I just received a notice that the ticket has been updated.

After looking at the ticket, I realized that I have forgoten

the existen of this ticket.

What I found was that I was indeed using a patcked kernel.

After replacing it with a fresh vanilla kernel, the lmsensor works

perfecctly. In fact, I tried the lmsensor with vanilla kernel on

both of my SMP machines, no problem at all!

Sorry about the trouble!!

Thanks for your support,

Barku
