These lock ups will cause the entire machine to freeze, but a single press on the keyboard will cause the machine to continue as if nothing had happened. The machine's services are still active though, and if I ssh in to the machine there are two apparent problems; the input/output 'lags' behind (that is, when I type 'ls', I have to press return twice to see the output, the two returns are still processed as two returns, but it seems like I lag one command behind all the time) and that the machines clock is acting weird. When typing 'date', I noticed that the time seemed to wrap around after 8 seconds; e.g. say the clock is '16:40:10'. After 6 seconds the clock is, not surprisingly, '16:40:16'; but after 8 seconds it's '16:40:10' again. I'm not sure it's exactly 8 seconds though, as I've only had the chance of verifying this once. I've narrowed it down (I think) to the maestro driver as these lockups only happen when I play music. It doesn't matter if I use mplayer from console, or xmms from X, the lockups still happen. These lockups doesn't happen if I don't play music, so... This started to happen a couple of months ago. More information can be obtained if you ask me. It's very easy to reproduce the problem (as it happens several times a day), so I can test various hacks if you have any. Please CC me any replies, I only read the list filtered through kernel-traffic. ;) //F The machine is an Compaq Armada M700, with an Maestro 2E soundcard: maestro: Configuring ESS Maestro 2E found at IO 0x3000 IRQ 11 maestro: subvendor id: 0xb1120e11 maestro: not attempting power management. maestro: AC97 Codec detected: v: 0x83847609 caps: 0x6940 pwr: 0xf maestro: 1 channels configured. maestro: version 0.15 time 08:33:02 Mar 5 2003 ver_linux output: Linux wolverine.xmen 2.4.20-gentoo-r1 #2 Wed Mar 5 08:15:06 CET 2003 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux Gnu C 3.2.2 Gnu make 3.80 util-linux 2.11y mount 2.11y modutils 2.4.25 e2fsprogs 1.32 reiserfsprogs 3.6.4 Linux C Library 2.3.1 Dynamic linker (ldd) 2.3.1 Procps 2.0.10 Net-tools 1.60 Kbd 1.06 Sh-utils 2.0.15 Modules Loaded nls_iso8859-1 floppy thermal processor fan button battery ac maestro hid uhci usbcore keybdev mousedev input proc/iomem: 00000000-0009fbff : System RAM 0009fc00-0009ffff : reserved 000a0000-000bffff : Video RAM area 000c0000-000c7fff : Video ROM 000d0000-000d17ff : Extension ROM 000f0000-000fffff : System ROM 00100000-13feffff : System RAM 00100000-002c496c : Kernel code 002c496d-00348aff : Kernel data 13ff0000-13ff37ff : reserved 13ff3800-13ffffff : ACPI Non-volatile Storage 40000000-410fffff : PCI Bus #01 40000000-40ffffff : ATI Technologies Inc Rage Mobility P/M AGP 2x 41000000-41000fff : ATI Technologies Inc Rage Mobility P/M AGP 2x 41100000-41100fff : Texas Instruments PCI1450 41180000-41180fff : Texas Instruments PCI1450 (#2) 41200000-4121ffff : Intel Corp. 82557/8/9 [Ethernet Pro 100] 41280000-41280fff : Intel Corp. 82557/8/9 [Ethernet Pro 100] 41280000-41280fff : eepro100 41300000-41300fff : Lucent Microelectronics LT WinModem 50000000-53ffffff : Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge
