>Description:
I met 100% reproducible kernel panic when DEVICE_POLLING is enabled and sound sustem is active.
If I enable polling for my em0 using ifconfig/rc.conf, start playing audio, and in parallel, start to download some stuff with full speed of my internet connection - there is always the same result - kernel panics. All this conditions (polling+audio+download) should be achieved in one time to generate panic.
My sound card is SB Live and I use snd_emu10k1 driver (compiled in or loaded as module). To test this problem, I have builded GENERIC kernel with this set of options:
options DEVICE_POLLING
options HZ="1000"
kldstat:
Id Refs Address Size Name
1 10 0xc0400000 b51968 kernel
2 1 0xc0f52000 85a4 snd_emu10k1.ko
3 3 0xc0f5b000 4836c sound.ko
4 1 0xc0fa4000 6722c acpi.ko
5 1 0xc4b31000 2000 rtc.ko
6 1 0xc4b33000 21000 linux.ko
my make.conf is:
PERL_VER=5.8.8
PERL_VERSION=5.8.8
CPUTYPE=pentium4
CFLAGS+= -pipe
COPTFLAGS+= -pipe
mp3 audio playing has been done using XMMS from KDE, and mocp/mpg321 from console. Audio has been played from regular user account.
xmms-1.2.11_2
moc-2.4.1_3
mpg321-0.2.10_7
My Internet connection is DSL line with 230KB/64KB speed. Panics occur then I fill up this channel with http download trafic. There is no firewall in kernel/modules loaded during tests.

>How-To-Repeat:
1) Build/install GENERIC kernel with options:
options DEVICE_POLLING
options HZ="1000"
2) /boot/loader.conf
snd_emu10k1_load="YES"
3) ifconfig em0 polling
4) mpg321 ./some_nice_audio.mp3
5) fetch http://some.site.com/some_big_file
