I installed Ubuntu 23.10 server into a new VM and also all packages that are needed to build the kernel and run blktests. This is how I ran the srp/002 test: # (cd .../blktests && i=0 && while true; do ((i++)); echo ==== $i; ./check srp/002; done) With kernel v6.5-rc7, 40 iterations ran fine without triggering any hang. I haven't found any kernel commits between v6.5-rc3 and v6.5-rc7 that could explain a behavior change for the SRP tests so I'm not sure why we are seeing different results on our test setups ... Thanks, Bart.
