I can't find any warning statement near line 2249 in ib_srpt.c. What ib_srpt version are you using?


Thanks,


Bart.



this is scst 3.6.  it's not the latest; but it's what we test and qualify with our other products.  that warning is from srpt_unregister_ch(), which seems to be only in new versions.
