[ewg] Problem with ABI mismatch for libibverbs

[Steve Wise]

Hey ofa developers,

My QA group is seeing problems running ofed-1.5.3-rc1 on a 32b system with 2.6.34 kernel.  It seems the core drivers 
aren't setting up the abi version correctly.   The library wants ABI version 6, but when they cat 
/sys/class/infiniband_verbs/abi_version it returns nothing.  So whenever they try to use an rdma app, they see this error:

olive:~ # rping -svd
libibverbs: Fatal: kernel ABI version 0 doesn't match library version 6.
CMA: unable to get RDMA device list
rdma_create_event_channel: No such device
olive:~ # cat /sys/class/infiniband_verbs/abi_version
olive:~ #



Any ideas?

BTW: This is ofa bug 2193.


Thanks,

Steve.
