Description Yury Konovalov 2007-01-15 08:52:36 UTC

IBM's POWER platform Infiniband HCA driver (ehca) refuses to load. Do I need to
load some special driver before ehca?

---------

How reproducible: always


Steps to Reproduce:
1. modprobe ehca
  
Actual results:
eHCA Infiniband Device Driver (Rel.: SVNEHCA_0015)
 
PU0003 EHCA_ERR:hipz_h_query_hca response_block=c0000001dcdd5680 not page aligned
 
PU0003 EHCA_ERR:ehca_sense_attributes Cannot query device properties.
h_ret=fffffffffffffffc
 
PU0003 EHCA_ERR:ehca_probe Cannot sense eHCA attributes.
 
ehca: probe of .001.DPM1PVW-P1-C21 failed with error -22



Expected results:
initialize Infiniband adapter.

This should have been fixed with the RHEL5.1 kernel update.  If it wasn't, then
please re-open the bug.
