Hello friends, tonight I've decided to upgrade my kernel because of the security issues recently discovered. I was using 2.4.22.2129.nptl and upgraded to 2.4.2140.nptl - And installed 2.6.1 also - all via synaptic. After the boot, the system would not boot anymore, with 2.4.22.2140 or 2.6.1.?? . The message follows: Loading ext3.o module Mounting /proc filesystem Mounting /sysfs Mount: error 19 mounting sysfs Creating block devices VFS: Cannot open root device "LABEL=/" or 00:00 Please append a correct "root=" boot option Kernel Panic: VFS: Unable to mount root fs on 00:00 I've changed /etc/grub.conf so the line now is kernel /vmlinuz-2.4.22-1.2140.nptl ro root=/dev/hda2 hdc=ide-scsi rhgb which means I've changed from "LABEL=/" to /dev/hda2, and now it boots, but... I see this on boot: EXT2-fs warning (device ide0(3,2)): ext2_read_super: mounting ext3 filesystem as ext2 Sound is gone also. I was using ALSA, but now this happens: [root@casa archives]# modprobe snd-via82xx;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: unresolved symbol schedule_work /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod snd-via82xx failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: unresolved symbol schedule_work /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod snd-pcm-oss failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: unresolved symbol schedule_work /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod snd-mixer-oss failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: unresolved symbol schedule_work /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o failed /lib/modules/2.4.22-1.2140.nptl/kernel/sound/snd.o: insmod snd-seq-oss failed And the machine became noticeably slower. Can someone help me understand what the h&ll happened here? -- []s Alexandre Ganso 500 FOUR vermelha - Diretor Steel Goose Moto Group
