Here's with linux_kdump:

    658 srcds_amd CALL  gettimeofday(0xbfbfc5d0,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  linux_socketcall(0x5,0xbfbfb4d0)
    658 srcds_amd RET   linux_socketcall -1 errno 11 Resource deadlock avoided
    658 srcds_amd CALL  gettimeofday(0xbfbfc5e0,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  gettimeofday(0xbfbfc5b0,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  linux_socketcall(0xc,0xbfbe4d40)
    658 srcds_amd RET   linux_socketcall -1 errno 11 Resource deadlock avoided
    658 srcds_amd CALL  gettimeofday(0xbfbfb4c0,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  gettimeofday(0xbfbfc590,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  gettimeofday(0xbfbfc5b0,0)
    658 srcds_amd RET   gettimeofday 0
    658 srcds_amd CALL  nanosleep(0xbfbfc830,0)
    658 srcds_amd RET   nanosleep 0
    658 srcds_amd CALL  linux_select(0x1,0xbfbfc670,0,0,0xbfbfc5e8)
    658 srcds_amd RET   linux_select 1

Strange, though, is linux_socketcall() the culprit for the strange 
error, or is it something else?
