I'm runing a 2.4.20 kernel compiled with gcc-2.95.3. I compiled and tried the last 3 releases of the alsa driver, lib and utils and i get always the same=20 kernel panic. My lsmod says : Module Size Used by Not tainted snd-seq-midi 4096 0 (autoclean) (unused) snd-seq-oss 29152 0 (unused) snd-seq-midi-event 3336 0 [snd-seq-midi snd-seq-oss] snd-seq 37648 2 [snd-seq-midi snd-seq-oss snd-seq-midi-event] snd-pcm-oss 39108 0 (unused) snd-mixer-oss 13720 0 [snd-pcm-oss] snd-ens1371 11660 0 snd-pcm 62432 0 [snd-pcm-oss snd-ens1371] snd-page-alloc 5244 0 [snd-pcm] snd-timer 14824 0 [snd-seq snd-pcm] snd-ac97-codec 39240 0 [snd-ens1371] snd-rawmidi 14048 0 [snd-seq-midi snd-ens1371] snd-seq-device 4368 0 [snd-seq-midi snd-seq-oss snd-seq snd-rawmidi]snd 31748 4 [snd-seq-midi snd-seq-oss snd-seq-midi-event snd-seq snd-pcm-oss snd-mixer-oss snd-ens1371 snd-pcm snd-timer snd-ac97-codec snd-rawmidi snd-seq-device] soundcore 3620 8 [snd] and when i ` cat file.wav > /dev/audio` i get : Unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c0111f13 *pde =3D 00000000 Oops: 0000 CPU: 0 EIP: 0010:[] Not tainted EFLAGS: 00010097 eax: ed9a1984 ebx: ed9a1984 ecx: 00000000 edx: 00000003 esi: ed9a1988 edi: 00000001 ebp: eda59f2c esp: eda59f14 ds: 0018 es: 0018 ss: 0018 Process alsamixer (pid: 14413, stackpage=EDa59000) Stack: eb007cc0 ed27cac0 ed9a1800 ed9a1988 00000286 00000003 ed9a194c f89a1511 eae425c0 00000286 ed9a195c e54499c0 ed9a195c e54499c0 f89a304d ed9a1800 ed27cac0 00000000 e54499e0 ed9a195c ed27cac0 eae425c0 c1c1e380 e2114dc0 Call Trace: [] [] [] [] [] [] Code: 8b 01 85 45 fc 74 4c 31 c0 9c 5e fa c7 01 00 00 00 00 83 79 Segmentation fault and it doesn't return after that. I tried to start alsamixer and i got the same thing, but it retrund to the shell this time, so i was able to copy this output. I compiled the soundcore and es1371 as loadable kernel modules. Loading them and the other alsa modules is no problem. I hope i made my self clear and gave you enough info to help me on this one. Thanks alot, Iqbal --=20 echo "[q]sa[ln0=3Daln256%Pln256/snlbx]sb9110849205086363247337574050075\ 032905184391195412274100697358608023133864165787933915045683432087129\ 472907338347329339706073226139582008068077725378669120069632snlbxq"|dc
