Dear sir, Today I upgrade my kernel from 2.4.21-ac1 to 2.4.22-pre6 and alsa-drivers from 0.9.4 to 0.9.5. Every thing work well but I can't play musics. :: dmesg :: Intel 810 + AC97 Audio, version 0.24, 11:19:13 Jul 16 2003 i810_rng: RNG not detected :: /var/log/message :: Jul 16 13:59:36 MrChoke kernel: Intel 810 + AC97 Audio, version 0.24, 11:19:13 Jul 16 2003 Jul 16 13:59:36 MrChoke pci.agent: ... can't load module i810_audio Jul 16 13:59:36 MrChoke pci.agent: missing kernel or user mode driver i810_audio Jul 16 13:59:36 MrChoke pci.agent: ... can't load module i810_rng Jul 16 13:59:36 MrChoke pci.agent: missing kernel or user mode driver i810_rng I trie modprobe i810_rng but not success. /lib/modules/2.4.22-pre6/kernel/drivers/char/i810_rng.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg With last kernel I never do above. I use oldconfig from 2.4.21-ac1. :: My labtop :: Toshiba 2410 Gentoo linux 00:1f.5 Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio Controller (rev 02) :: lsmod :: Module Size Used by Tainted: P snd-mixer-oss 13752 1 (autoclean) hid 22020 0 (unused) uhci 26800 0 (unused) ohci1394 31240 0 (unused) ieee1394 48420 0 [ohci1394] snd-intel8x0 18756 1 snd-mpu401-uart 3472 0 [snd-intel8x0] snd-rawmidi 13920 0 [snd-mpu401-uart] snd-seq-device 4336 0 [snd-rawmidi] snd-ac97-codec 41256 0 [snd-intel8x0] snd-pcm 62944 0 [snd-intel8x0] snd-timer 14852 0 [snd-pcm] snd 30948 0 [snd-mixer-oss snd-intel8x0 snd-mpu401-uart snd-rawmidi snd-seq-device snd-ac97-codec snd-pcm snd-timer] snd-page-alloc 6548 0 [snd-intel8x0 snd-pcm] nvidia 1541984 10 usbmouse 2264 0 (unused) mousedev 4404 1 ide-scsi 10480 0 Thank MrChoke ===== :: .config ::
