Hi,
I was wondering if anyone has seen or has a patch for this oops? We
just switched to the suse 2.6.16 kernel, lustre 1.4.9, with OFED-1.1.
We're using the mthca device. Part of the lnet debug log is below (note
that the line numbers are 3 greater than what's in the lustre 1.4.9 source).
thanks,
pau
