Oops with >= 2.4.0-test7 when modprobing gus module
Hello, Whenever I modprobe the gus module the kernel gives an oops: Gravis Ultrasound audio driver Copyright (C) by Hannu Savolainen 1993-1996 at 0x240 irq 3 dma 1,5 Unable to handle kernel NULL pointer dereference at virtual address The module is loaded after that, and the soundcard is functioning as it should. However, the refcount of the module is all wrong and it can't be removed anymore. The full oops (processed by ksymoops) is attached. --- Met vriendelijke groet / with kind regards, Guus Sliepen <[EMAIL PROTECTED]> --- See also: http://tinc.nl.linux.org/ http://www.kernelbench.org/ --- ksymoops 2.3.4 on i586 2.4.0-test8.
