Hi All, I am seeing this problem as well: a. The kernel is in a tight loop via the fxp driver since there are frames that need to be DMA'd but cannot be because 'b.' b. The fxp driver calls m_getcl( ) which returns ENOBUFS since there are no clusters to satisfy the request. This goes on constantly so it appears the system is hung. I submitted a follow-up to the PR and also requested contact with a committer to discuss this problem and possible solutions. I think this should be fixed, right away. If you would like to donate your 2 cents worth to this discussion; I = would be very happy to hear from you and am grateful for the input.
