>Description:
After system startup, hald smothness (in 1 minute after system boot) get system usage to 100% (my system have 4 core, so one of them is fully under hald):
(head lines from "TOP -P" command):

(100% load from hald do not depend on working/not working Xorg)
If i've doing (from root user) command
truss -p 1340
where 1340 - pid of hald
i see repeating output:
---
poll({5/POLLIN 9/POLLIN 11/POLLIN|POLLPRI 16/POLLIN 7/POLLIN 10/POLLIN 8/POLLIN 88/POLLIN 13/POLLIN},9,588) = 1 (0x1)
gettimeofday({1237915288.562078 },0x0) = 0 (0x0)
read(13,0x7fffffffe6f0,400) = 0 (0x0)
gettimeofday({1237915288.562149 },0x0) = 0 (0x0)
poll({5/POLLIN 9/POLLIN 11/POLLIN|POLLPRI 16/POLLIN 7/POLLIN 10/POLLIN 8/POLLIN 88/POLLIN 13/POLLIN},9,588) = 1 (0x1)
gettimeofday({1237915288.562232 },0x0) = 0 (0x0)
read(13,0x7fffffffe6f0,400) = 0 (0x0)
gettimeofday({1237915288.562304 },0x0) = 0 (0x0)
poll({5/POLLIN 9/POLLIN 11/POLLIN|POLLPRI 16/POLLIN 7/POLLIN 10/POLLIN 8/POLLIN 88/POLLIN 13/POLLIN},9,588) = 1 (0x1)

and after this command, 100% load of core magically is smothness fall to 0.00% usage with changing "STATE" to STOP in TOP screen:
1340 haldaemon 1 76 0 42148K 6640K STOP 1 10:14 0.00% hald
But mouse/keyboard working fine (if i've stoping hald, then mouse is dying)
>How-To-Repeat:
I've reproduce this situation on 8-HEAD (kern.osrevision: 199506) with USB2.0 support (all soft & kernel & usernanld has been recompile after changing USB stack, old libusb.so remove and "Legacy USB support (1.0) disabling in Bios)
Version of hal: hal-0.5.11_21
