Hi @rwg1335252904 ,
There are many reasons may cause this issue.
The module smc depends on ib_core.
- Check version
Use these commands:
(1) uname -r
(2) modinfo ib_core
(3) modinfo smc
Make sure that the vermagic version shown in the output of the modinfo command is the same as the output of uname -r .
- Verify which ib_core.ko to use
After installing OFED, there might be multiple files named ib_core.ko, such as:
/var/lib/dkms/mlnx-ofed-kernel/*/module/ib_core.ko/usr/lib/modules/*/kernel/drivers/infiniband/core/ib_core.ko/usr/lib/modules/*/updates/dkms/ib_core.ko
Check which ib_core.ko you are using with command modinfo ib_core.
Then you may need to recompile smc.ko with the right Module.symvers:
/usr/src/linux-headers-$(uname -r)/Module.symvers/usr/src/ofa_kernel/x86_64/$(uname -r)/Module.symvers
You can try them out and find out which is the right one.
Then you can insert the newly compiled smc.ko using insmod .
Best regards!
