the sound module snd-nm256 causes lockup (hard) on (un)load. this happens with every kernel i have tried. incl the newest development (see emerge -info && uname -a) the alsa package will 80% of the time also cause a hard lock on boot @ calculating module dependancies. (no log output >> hard lock..) this occurs with both alsa and oss. aether neo # lspci -v 0000:00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) Flags: bus master, medium devsel, latency 32 Memory at f4000000 (32-bit, prefetchable) [size=64M] Capabilities: [a0] AGP version 1.0 0000:00:01.0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) (prog-if 00 [Normal decode]) Flags: bus master, 66Mhz, medium devsel, latency 32 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000c000-0000cfff Memory behind bridge: fd000000-feffffff Prefetchable memory behind bridge: f8000000-fbffffff 0000:00:03.0 CardBus bridge: Texas Instruments PCI1225 (rev 01) Subsystem: Dell: Unknown device 0091 Flags: bus master, medium devsel, latency 168, IRQ 11 Memory at 10100000 (32-bit, non-prefetchable) [size=4K] Bus: primary=00, secondary=02, subordinate=05, sec-latency=176 Memory window 0: 12000000-13fff000 (prefetchable) Memory window 1: 14000000-15fff000 I/O window 0: 00001000-00001fff I/O window 1: 00002000-00002fff 16-bit legacy interface ports at 0001 0000:00:03.1 CardBus bridge: Texas Instruments PCI1225 (rev 01) Subsystem: Dell: Unknown device 0091 Flags: bus master, medium devsel, latency 168, IRQ 11 Memory at 10101000 (32-bit, non-prefetchable) [size=4K] Bus: primary=00, secondary=06, subordinate=09, sec-latency=176 Memory window 0: 16000000-17fff000 (prefetchable) Memory window 1: 18000000-19fff000 I/O window 0: 00003000-00003fff I/O window 1: 00004000-00004fff 16-bit legacy interface ports at 0001 0000:00:07.0 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02) Flags: bus master, medium devsel, latency 0 0000:00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01) (prog-if 80 [Master]) Flags: bus master, medium devsel, latency 32 I/O ports at 0860 [size=16] 0000:00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01) (prog-if 00 [UHCI]) Flags: bus master, medium devsel, latency 32, IRQ 11 I/O ports at ece0 [size=32] 0000:00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03) Flags: medium devsel, IRQ 9 0000:01:00.0 VGA compatible controller: Neomagic Corporation NM2360 [MagicMedia 256ZX] (prog-if 00 [VGA]) Subsystem: Dell: Unknown device 0091 Flags: bus master, medium devsel, latency 32, IRQ 11 Memory at fa000000 (32-bit, prefetchable) [size=32M] Memory at fdc00000 (32-bit, non-prefetchable) [size=4M] Memory at fdb00000 (32-bit, non-prefetchable) [size=1M] Capabilities: [dc] Power Management version 1 0000:01:00.1 Multimedia audio controller: Neomagic Corporation NM2360 [MagicMedia 256ZX Audio] Subsystem: Dell: Unknown device 0091 Flags: medium devsel, IRQ 5 Memory at f9800000 (32-bit, prefetchable) [disabled] [size=8M] Memory at fda00000 (32-bit, non-prefetchable) [disabled] [size=1M] Capabilities: [dc] Power Management version 1 0000:02:00.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03) Subsystem: Linksys WPC54G Flags: bus master, fast devsel, latency 64, IRQ 11 Memory at 14000000 (32-bit, non-prefetchable) [size=8K] Capabilities: [40] Power Management version 2 aether neo # uname -a Linux aether 2.6.13-gentoo-r3 #5 Fri Nov 4 14:44:07 UTC 2005 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux Reproducible: Always Steps to Reproduce: 1.install gentoo on dell latitude csx 2.build kernel w/ either alsa or oss 3.modprobe snd-nm256 Actual Results: hard lock. power cycle necessary, no log output, no dmesg output.

testing semi-applied patch as indicated in last update.. will commit incase of lock. next replay will indicate success/failure..
the patch *did* work. i loaded the modules with no problems, and i now have sound. do not know how reliable this is as i have not tried to unload it. please have a look at that patch, and maby include it in a future release?
update... this is NOT a solution.. it made the problem intermittant is all.
Please test vanilla-sources-2.6.15_rc2 -- this patch has already been applied there.
This should be fixed in the recent releases as the patch was merged into linux-stable. Please reopen with new info if not.
