[openib-general] Re: Failure in reset HCA with backport-svn4507-to-2.6.9

[Ranjit Pandit]

I'm having the same problem with the kernel that Redhat posted

"kernel-smp-2.6.9-22.14.EL.OpenIB_3965.3.i686.rpm"

from:

http://people.redhat.com/dledford/Infiniband/RHEL-4/kernel/2.6.9-22.14.EL.OpenIB_3965.3/i686/

Again, I know that the card is functional.
