Hi all. When I executed "netperf" by a short message of UDP, PV domain issued Call trace.
I think that GrantEntry was filled with a lot of messages processings. This problem is generated in IA64 only. I corrected to check "number of unprocessing queue > tx_queue_len" before Grant was filled. Is there other a good correction? -------------------- # ./netperf -t UDP_STREAM -H 10.34.179.101 -l 3 -- -m 10 -M 10 netperf[2474]: bugcheck! 0 [1] Modules linked in: Pid: 2474, CPU 0, comm: netperf psr : 00001010081a2010 ifs : 8000000000000b9b ip : [<a0000001006c9ce0>] Not tainted ip is at network_start_xmit+0xa00/0xe40 unat: 0000000000000000 pfs : 8000000000000b9b rsc : 000000000000000b rnat: 0000000000000000 bsps: 0000000000000000 pr : 0104682415669999 ldrs: 0000000000000000 ccv : 0000000000000000 fpsr: 0009804c8a70033f csd : 0000000000000000 ssd : 0000000000000000 -------------------- Best regards, Tomonari Horikoshi
