Hmm, there seems to be some merging problems in changeset 1.44 for
qla_os.c -- the 'DMA pool/api usage' patch I sent is not completely
integrated (appears to be massaging problems while attempting to apply
on top off 1.43).

Please apply the attached patch which should address the issue.

Andrew Vasquez
