Hi,

after a while running my system load goes up by 3 apparently caused by
hald (http://www.freedesktop.org/software/hal/) locking up together with
[scsi_eh_1] and [usb-storage].

The activity LED of my USB 6in1 card reader flashes nervously and I
obtained the following task state using magic SysRQ:

hald          D 0000268216b1cdba     0  7996   3415                     (NO=

Anyone else seeing this problem?
