Can you check if it's specific to ib_srp? Is there a way to simulate
an ib_srp setup?
This infinite loop was due to the scsi_dh_alua handler not being
loaded during my test (as mentioned in
https://www.mail-archive.com/linux-scsi@xxxxxxxxxxxxxxx/msg42645.html).
So it works with that patch?
Hello Hannes,
Manually loading the scsi_dh_alua handler or adding the patch that loads
that handler again automatically indeed fixed the infinite loop. But I'm
still very concerned about the scalability issues caused by submitting
RTPG commands synchronously instead of asynchronously.
Bart.
