Subject: Oops caused by flashplayer using OSS emulation
Date: Sat, 18 Sep 2004 19:09:15 -0400 [thread overview]
Message-ID: <1095548954.9049.17.camel@krustophenia.net> (raw)
It's possible that this bug no longer exists, I believe this is a CVS
version of ALSA from between 1.0.5a and 1.0.6. This was caused by a
flash applet in mozilla.
Unable to handle kernel NULL pointer dereference at virtual address 00000000
