Run #36 with debug=0x0c ( P9_DEBUG_VFS | P9_DEBUG_9P). Hang occurs in autopkgtest at timestamp 10:56:44.002011 (UTC+1). In the guest kernel log that maps to timestamp 09:56:44.666943 where the first v9fs_file_read_iter(count=1000000, offset=0) occurs.

What is interesting is the reads fetch slightly more data before spinning at:

09:56:56.732407 v9fs_file_read_iter (885): fid 6 count 1000000 offset 7331840

Do we have a timing/race condition here?
