Thanks for the bug report. I'll take a look.

What are your mount options?

I tried many options, without changing the problem. For example I switched: directio,rsize,and these module configuration options: parm: CIFSMaxBufSize:Network buffer size (not including header). Default: 16384 Range: 8192 to 130048 (int) parm: cifs_min_rcv:Network buffers in pool. Default: 4 Range: 1 to 64 (int) parm: cifs_min_small:Small network buffers in pool. Default: 30 Range: 2 to 256 (int) parm: cifs_max_pending:Simultaneous requests to server. Default: 50 Range: 2 to 256 (int)
