Hi,
Please bear with me, it's my first bug report and my first post to this list. Bear with my english too.
[1.] One line summary of the problem: Bad PCI detection of a sound card
[2.] Full description of the problem/report: I think the problem is due to a bad PCI detection but i let you judge. Here is a description of the problem : I'm under X (Xfree 4.0.1). I switch to a VT (virtual terminal). I load my sound module (modprobe emu10k1). Dmesg says : Creative EMU10K1 PCI Audio Driver, version 0.7, 19:07:50 Nov 15 2000 PCI: Enabling device 00:0a.0 (0000 -> 0001) PCI: Setting latency timer of device 00:0a.0 to 64 emu10k1: EMU10K1 rev 8 model 0x8040 found, IO at 0xb400-0xb41f, IRQ 5 I try to play a sound (play some.wav). It works. I switch to X. In a xterm, i try to play a sound. The "Play" command hangs... I switch back to a VT. I unload sound modules (rmmod emu10k1 soundcore). I reload them. Dmesg says: Creative EMU10K1 PCI Audio Driver, version 0.7, 19:07:50 Nov 15 2000 emu10k1: EMU10K1 rev 8 model 0x8040 found, IO at 0xb400-0xb41f, IRQ 5 "Play" command works in the VT but not under X (same as before). Now i unload sound modules. I reload them under X. Dmesg says: Creative EMU10K1 PCI Audio Driver, version 0.7, 19:07:50 Nov 15 2000 PCI: Enabling device 00:0a.0 (0000 -> 0001) emu10k1: EMU10K1 rev 8 model 0x8040 found, IO at 0xb400-0xb41f, IRQ 5 Now "Play" command works under X and in the VT.
In brief : To be able to have sound working properly, i must load sound modules under X *and* load them in a VT. Order is not important, i can do: load from console/unload/load under X or load under X/unload/load in a VT it gives the same.
Other observations: If i load sound modules *only* in a VT, play a lengthy sound and switch to X while sound is playing, everything locks (I must use MagicSysKey to reboot), but nothing appears in logs. With kernel 2.2 (Debian 2.2.17, Mandrake 7.2 2.2.17 or 2.2.18pre21 compiled by myself), i cannot load module under X (device or ressource is busy) but i can load modules and play sounds in a VT (even if X is running).
