I've just updated the linux-generic package to 2.6.20.12.8 and I've removed the modules I put in /etc/initramfs-tools/modules file... then rebooted the PC and everything works like a charm :)
P.S.: I am still using the 2.6.20-11.18-generic kernel image. I'll upgrade the kernel image to 2.6.20-12.19 right now and see if it still works. -- modprobe abnormal exit - Kernel 2.6.20-8/9/10/11/12 does not boot https://launchpad.net/bugs/84964 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
