tcpdump hang and system gone in freeze state

[Varun Sharma]

Hi,

I build new kernel (2.6.32.60). when i execute tcpdump on this build kernel
,tcpdump gone in hang state and system gone in freeze state .


ltrace tcpdump output is---

__libc_start_main(0x452220, 1, 0x7fff623b6158, 0x462d70, 0x462d60
<unfinished ...>
strrchr("tcpdump", '/')                                = NULL
getopt(1, 0x7fff623b6158, "aAB:c:C:dDeE:fF:G:i:IKlLm:M:nNOp"...) = -1
time(NULL)                                             = 1373602325
gmtime(0x7fff623b5e68)                                 = 0x313eba03e0
localtime(0x7fff623b5e68)                              = 0x313eba03e0
getuid()                                               = 0
pcap_lookupdev(0x7fff623b5f30)                         = "eth0"
pcap_create(0x314d636140, 0x7fff623b5f30, 0x11f6690, 0x313eb9ce90, 11) =
0x11f6ac0
pcap_set_snaplen(0x11f6ac0, 65535, 0x8038a0, 0x306874, 0) = 0
pcap_set_promisc(0x11f6ac0, 1, 0, 0x306874, 0)         = 0
pcap_set_timeout(0x11f6ac0, 1000, 0, 0x306874, 0)      = 0
pcap_activate(0x11f6ac0, 0, 0, 0x306874, 0


tcpdump hang in pcap_activate . whereas if run tcpdump in original kernel
it works fine.can anybody know the reason?
