The effects are the same whether X is started or not. Setting debug.debugger_on_panic has no effect, the system just freezes. I've attached a "screen shot" of a garbled console screen. While trying this out, I found two other variations of this: 2) Module doesn't find sound card at first, system freezes at the second attempt to load the module: root@deimos:~ # kldload snd_hda pcm0: <NVidia MCP51 High Definition Audio Controller> mem 0xf2300000-0xf2303fff irq 21 at device 16.1 on pci0 pcm0: Audio Function Group not found! root@deimos:~ # kldunload snd_hda pcm0: detached root@deimos:~ # kldload snd_hda ==> freeze 3) Sort of a interrupt conflict when loading the module: pcm0: <NVidia MCP51 High Definition Audio Controller> mem 0xf2300000-0xf2303fff irq 21 at device 16.1 on pci0 pcm0: <HDA Codec: Realtek ALC260> pcm0: <HDA Driver Revision: 20071129_0050> intr 18 on cpu0 at 40001/40000 hz, livelocked limit engaged! And then keyboard and mouse are no longer usable as interrupt 18 is occupied by the usb controller: ohci0: <OHCI (generic) USB controller> mem 0xf2304000-0xf2304fff irq 18 at device 11.0 on pci0 When unloading the module via ssh, the system freezes as usual. ---------------------------------------- Bug #2308: System freeze when unloading snd_hda http://bugs.dragonflybsd.org/issues/2308 Author: Joachim de Groot Status: New Priority: Normal Assignee: Category: Target version: When unloading snd_hda, the system (v3.1.0.197.gcc1635-DEVELOPMENT) freezes completely. There is no panic; the screen just gets garbled and the system no longer responds to any interaction, may it be local or via network. This shows up when loading the module: pcm0: <NVidia MCP51 High Definition Audio Controller> mem 0xf2300000-0xf2303fff irq 21 at device 16.1 on pci0 pcm0: <HDA Codec: Realtek ALC260> pcm0: <HDA Driver Revision: 20071129_0050> -- You have received this notification because you have either subscribed to it, or are involved in it.
