I believe I have this problem with 1.5.14 with AFS as the root filesystem.. I've seen the problem during a make -j8. CMdebug just hangs, but rxdebug to port 7001 on the hung machine still works I ended up using 1.5.14 because recent kernels (2.6.19) changed the makefiles enough so that 'osi_flush.s' is no longer recognized on ppc64, and I was trying to figure out why it didn't work. Renaming osi_flush.s to osi_flush.S fixes it, so I'll try 1.4.x.. _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
