Kernel panic after update

eikakot · 2011-01-31 13:42:23

Hello, after updating my system I'm now getting this sweet kernel panic error. I found out that it is caused by netwokmanager daemon. When i remove networkmanager from rc.conf, i can get into my gnome environment. I've tried using network daemon instead of networkmanager , but with no luck. Here's what i've got:

Kernel panic - not syncing: map_single: bounce buffer is not DMA'ble
Pid: 1423, comm: ifconfig Tainted: P 2.6.37-ARCH #1

By the way I'm using Dell Inspiron 1720 laptop. Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)

Well i tried rolling back to previous kernel version but somehow everything got more messed up. First i had to remove nvidia package because nvidia requires kernel >= 2.6.37 so after removing nvidia i reinstalled the old kernel. When i rebooted, there was no kernel panics, but the system could not load a lot of modules, soundcard failed and stuff like that I couldnt get to gdm login screen. Then i tried to update system from command line and install nvidia again, but ive got error about finding no proxy server (i have to use one, due to university rules). So at this point it seems like nothing is working anymore Any suggestions?

did you do sudo mkinitcpio -p kernel26 after reinstalling the old kernel?

eikakot · 2011-01-31 20:11:08

yes. i hope im just missing somothing simple

I have the same problem on a Dell Inspiron 1520, and a broadcom chipset. Downgrading caused me similar headaches and I just didn't have time to resolve it, had to do work so I got stuck with booting into Windows XP, yuck. Other distros are affected:

I manage to "solve" the kernel panics this way I have a Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) and using b43 driver and b43-firmware

1.- If you are using compat-wireless drivers remove them
2.- Force reinstall of b43-fwcutter and b43-firmware
3.- Regenerate your initramfs ( sudo mkinitcpio -p kernel26 )
4.- Reboot

This was the only the kernel panics stopped

Having the same problem but not needing my Netbook immediately I guess there will probably be a bug fix soon?! To my knowledge this is a pretty popular chip set so it should be high on the agenda or is it "merely" a problem of correct configuration?

It looks like I'm not the only one with a broken system. I reverted to the 2.6.36-2 (whatever one was still in my cache) and the older nvidia package. Now it works; although, I don't really enjoy using older packages...

I have a Dell Inspiron 1720 with a Broadcom chip, probably the same one as eikakot (I'm not on it at the moment, so I can't check).

Does it work when switching to the b43 driver? This thread suggests that in my view but I haven't yet time to try maybe some of you guys have got any experience?

something similar on a old dell desktop
updated the kernel and now i get intermittent panics during boot
sometimes it boots sometimes not .

I just upgraded everything again. Wireless works fine, but when I try to connect via ethernet I get a kernel panic.

it turned out to be the udev bug
i was about to downgrade udev and decided to update first
the update did fix it

eikakot · 2011-02-08 13:14:55

I had the newest udev already so it seems to be a different problem than yours. I'm still getting kernel panic when trying to use ethernet with 2.6.37 kernel
When I do rrmod b44, I am able to use networkmanager and wireless. Sadly, there are no free wireless access points around here.

Now I'm using the kernel26-pf package which has a patch that fixes this issue. It works fine if you use the one in the AUR and add the line to apply the included patch (fixed). I'm glad I have ccache since I just compiled it twice... Now I don't get any kernel panics.
