I am getting the below trace on 2.6.17-rc2 / AMD x86_64 / PCIX HCA
with both the IB sources that come with the kernel and svn trunk 6520.
This happens if i just modprobe -r ib_mthca after fresh reboot, can
anyone reproduce it on her/his system as well? The module does get
modprobed out.
Or.
$ modprobe -r ib_mthca
$ dmesg

Hi Or,
I tested here on Intel x86_64 systems with kernel from Fedora C4 last
update (2.6.16-1.2069_FC4) and there was no issue in removing and
loading ib_mthca. I tested the code in IBED-1.0-rc3.
