Description

It looks current CDEBUG_LIMIT did not work well, after some 'git blame':
Regression comes from fdb5d3d50

-        if (cdls != NULL) {
-                if (libcfs_console_ratelimit &&
-                    cdls->cdls_next != 0 &&     /* not first time ever */
-                    !cfs_time_after(cfs_time_current(), cdls->cdls_next)) {
-                        /* skipping a console message */
-                        cdls->cdls_count++;
-                        if (tcd != NULL)
-                                cfs_trace_put_tcd(tcd);
-                        return 1;
-                }
+       if (cdls != NULL) {
+               if (libcfs_console_ratelimit &&
+                   cdls->cdls_next != 0 &&     /* not first time ever */ 
+                   time_after(jiffies, cdls->cdls_next)) { ------->check logic is wrong here.
+                       /* skipping a console message */
+                       cdls->cdls_count++;
+                       if (tcd != NULL)
+                               cfs_trace_put_tcd(tcd);
+                       return 1;
+               }
 

After fixing above wrong check, problem is gone.
