[ 135.688260] Fixing recursive fault but reboot is needed!
System:
VIA SN18000G epia C7 with 4GB of ram
lpc-ntpd is a atomic clock receiver driver doing read()-calls on an fd
from a serial device (connected via usb), nothing fancy
(http://vanheusden.com/lpc-ntpd/ ).
This oops is very much reproducable using the following script:
pyk-perl.mod:
=----------=--------------------------------------------------
#! /usr/bin/perl -w
use POSIX;
@mods = <>;
for(;;)
{
$n = floor(rand(@mods));
print $mods[$n]."\n";
if (rand(2) < 1.0)
{
system('rmmod ' . $mods[$n]);
}
else
{
system('modprobe ' . $mods[$n]);
}
}
--------------------------------------------------------------
invoked with:
lsmod | grep -v -e via_rhine -v -e mii | awk '{ print $1; }' | ./pyk-perl.mod

cannot read device status, Broken pipe (32)
Isn't that error odd?

I submitted a patch for this:
http://marc.info/?l=linux-usb&m=122461735606713&w=2
It hasn't been merged yet, in any tree.

I'm a bit hesitant to add it for .28, especially as this isn't a
