Kerrnel drivers reset loading process

[SteveRiley]

Generally, DKMS is installed by higher-level packages that are designed to work with it.

[robijf]

I have checked: dkms is installed. Do I have to do anything in particular, maybe issue a command?

[robijf]

By googling around, I found the proper drivers for the RTL8188CE card that is installed.

Following instructions there, I did issued a make command, and then a make install command. Everything works perfectly, except the manual loading described here: http://www.kubuntuforums.net/showthr...ireless-module

[SteveRiley]

Would the installation of dkms help here?

I don't have any hardware with Realtek chips so I'm not sure whether drivers need to be compiled during installation.

Would the installation of dkms help here?

I have removed the virtual image, as suggested, but the wireless module problem is still there, I guess it has something to do with a config file, because I changed the kernel to linux-image-3.2.0-35-generic, and the problem is still there. Not even an upgrade did fix it. So I opened a new thread in the networking section of version 12.10. Thank you very much for your help

[SteveRiley]

First, there's nothing wrong with your file systems. errors=remount-ro is a mount option that tells the kernel to mount the filesystem in read-only mode only if an error is detected during boot. That's part of the default *buntu install.

Second, remove that virtual kernel, it isn't doing anything useful:

sudo apt-get purge linux-image-3.2.0-35-virtual

Third, will the module auto-load on any of those 3.2 kernels?

[robijf]

These are the installed kernels:

I'm running currently the 3.5.0-22-generic kernel. I think things went wrong trying to fix the wireless card.

I managed to install the rtl8192ce driver for the wireless card, but does not start automatically, I do have to do modprobe rtl8192ce to load the module. I'm googling to find a solution.

[SteveRiley]

Good catch -- indeed, the -virtual kernels should be used only when running Linux in a virtual machine. This is likely the reason you're having the problem.

It's easy to fix. But before I make a specific suggestion, I'd like to see a list of all kernels currently installed. Please show the output of

dpkg -l | grep linux-image

Problem partially solved

It seems all the trouble started when vmlinuz-3.2.0-35-virtual iimage was loaded.

I started the machine, held down RIGHT SHIFT key, selected an older version, i.e. vmlinuz-3.2.0-35-generic.

I would like to thank all of those who contributed to solving this problem.

It remains the problem of wireless network unclaimed.

[robijf]

I found the following in /var/log/syslog after the above alterations:

Linux version 3.2.0-35-virtual (build@allspice) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) #55-Ubuntu SMP

and

Command line: BOOT_IMAGE=/boot/vmlinuz-3.2.0-35-virtual root=UUID=... ro quiet splash vt.handoff=7

Is this a virtual image loading? How can I change which image to load on start?

[robijf]

I did some changes to /etc/fstab and replaced errors=remount-ro 0 1 with defaults 0 0 but the problem persists. Both networks are still unclaimed, the problems with driver loading persists.

[robijf]

It seems that an error occurred and there is a record in /etc/fstab "UUID=... / ext4 errors=remount-ro 0 1"

The command tune2fs -c 0 -i 0 /dev/sda1 has no effect:

tune2fs 1.42 (29-Nov-2011)
Setting maximal mount count to -1
Setting interval between checks to 0 seconds

touch /forcefsck and shutdown -r now restart the system without a force-check of the hard drive. The record in /etc/fstab is still there.

I found a few lines in /var/log/syslog:


Jan 17 09:30:37 robijf-SATELLITE-C850-127 kernel: [ 23.531008] EXT4-fs (sda1): re-mounted. Opts: errors=remount-ro

is this your / drive ?

having the system mounted ro (read only) could cause your problems.
