So I left it on for the weekend and by this morning there was still no errors, so I rebooted it and again saw the "ath1: unable to start recv logic" message for ath1 and ath2. I power cycled it, but still get the error, so Friday was just lucky with some timing thing, maybe if the card receive while it is still configuring? Also if I leave the board booted in this state, ath0 also start to give problems: ################# ath0: ath_rx_proc: no mbuf! ath0: ath_rx_proc: no mbuf! ... ath0: device timeout ath0: ath_reset: unable to start recv logic ... ################# In anycase it seems that memory allocation problem. How do I figure out where it is? "netstat -m" does not seem to point to an error. The mbuf info in vmstat -z also look ok. It is only "256 Bucket" in vmstat -z that point to an alloc failure. How do I figure out where that is and how do I fix it or work around it? ################### tst-11-arm:~ # netstat -m 128/382/510 mbufs in use (current/cache/total) 127/129/256/7654 mbuf clusters in use (current/cache/total/max) 127/126 mbuf+clusters out of packet secondary zone in use (current/cache) 0/0/0/3827 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/1134 9k jumbo clusters in use (current/cache/total/max) 0/0/0/637 16k jumbo clusters in use (current/cache/total/max) 286K/353K/639K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for mbufs delayed (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters delayed (4k/9k/16k) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/3/1488 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile tst-11-arm:~ # vmstat -z | grep mbuf mbuf_packet: 256, 48990, 127, 126, 2294, 0, 0 mbuf: 256, 48990, 1, 256, 920, 0, 0 mbuf_cluster: 2048, 7654, 253, 3, 253, 0, 0 mbuf_jumbo_page: 4096, 3827, 0, 0, 0, 0, 0 mbuf_jumbo_9k: 9216, 1134, 0, 0, 0, 0, 0 mbuf_jumbo_16k: 16384, 637, 0, 0, 0, 0, 0 mbuf_ext_refcnt: 4, 0, 0, 504, 1, 0, 0 tst-11-arm:~ # vmstat -z | grep Bucket 4 Bucket: 16, 0, 7, 497, 1565, 0, 0 6 Bucket: 24, 0, 0, 0, 0, 0, 0 8 Bucket: 32, 0, 3, 375, 83, 0, 0 12 Bucket: 48, 0, 2, 334, 5, 0, 0 16 Bucket: 64, 0, 14, 301, 43687, 16, 0 32 Bucket: 128, 0, 7, 148, 196, 0, 0 64 Bucket: 256, 0, 19, 56, 77, 0, 0 128 Bucket: 512, 0, 16, 16, 48, 0, 0 256 Bucket: 1024, 0, 29, 3, 1521,86738, 0 tst-11-arm:~ # ################### Regards John -- John Hay -- jhay@meraka.csir.co.za / jhay@meraka.org.za / jhay@FreeBSD.org
