Bug report: snd_pcm_oss crash (in pcm_pcm_format_silence)

Hey, snd_pcm_oss (I think) just crashed on me. Included dmesg output as
attachment. It happened when ogg123 finished playing, has never happened
to me before. Additionally, alsamixer was running on a different tty.

Sound hardware: Intel Corp. 82801CA/CAM AC'97 Audio Controller
Kernel version: 2.6.0-test7 (vanilla + nvidia + linux_wlan_ng)
Loaded modules:
prism2_pci
p80211
irda
snd_intel8x0
snd_ac97_codec
snd_mpu401_uart
snd_rawmidi
snd_seq_device
snd_pcm_oss
snd_pcm
snd_page_alloc
snd_timer
snd_mixer_oss
snd

Couldn't reproduce the bug, didn't try too much though.
