Ok, first let's see if this is due to the recent tgt changes or not;
0.9.8 and RHEL 5.3 initiator work?


> First, with TCP, I can't login, the initiator complains and prints the  "Could not create connection due to crc32c loading error. Make sure the crc32c module is built as a module or into the kernel" famous crc32 load error, but the RHEL 5.3  config file has it all in place (info below), I am quite sure its RTFM but I don't find the "M" that would tell me what I am doing wrong...

Wired, seems crc32c is built in.
