Hi, there,
recently I installed 12.04 Ubuntu on my laptop after a failed update and everything was ok.
Ubuntu updater (the source of all evils as it was responsible for that update from 10.04!) informed me to install proprietary drivers for my wireless card which I accepted unfortunately.
Next day the machine couldn't boot and I noticed messages on black screen saying about Hzs and I realized it was my network card drivers responsible.
As I searched the net and the man pages I saw that this command (print or control the kernel buffer) contains my black screen messages:
Code:
root#dmesg -k

I tried to list kernel modules but no entry with
'ath' or
'ndis':
Code:
root# lsmod | grep -e 'ath.*' -e 'ndis.*'
I tried to see what is blacklisted
Code:
root# less /etc/modprobe.d/blacklist-firewire.conf
# Select the legacy firewire stack over the new CONFIG_FIREWIRE one.
blacklist ohci1394
blacklist sbp2
blacklist dv1394
blacklist raw1394
blacklist video1394
#blacklist firewire-ohci
#blacklist firewire-sbp2
I tried to see the effective configuration of kernel modules related with
'ath' and I saw a message for macs (
my laptop is acer aspire):
Code:
root# modprobe -c | egrep -i 'ath.*'
# For some Atheros 5K RF MACs, the madwifi driver loads buts fails to
# which ath5k cannot recover. To prevent this condition, stop
blacklist ath_pci
...................
Should I blacklist 'ath5k' and 'ath9k'?
Is this the problem?
Can I remove 'ath5k' and 'ath9k' modules altogether? (don't care about wireless in my machine)
My list of kernel modules is this one:
Code:
root# modprobe -l ath*
kernel/drivers/net/wireless/ath/ath5k/ath5k.ko
kernel/drivers/net/wireless/ath/ath9k/ath9k.ko
kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko
kernel/drivers/net/wireless/ath/ath9k/ath9k_common.ko
kernel/drivers/net/wireless/ath/ath9k/ath9k_htc.ko
kernel/drivers/net/wireless/ath/ath6kl/ath6kl.ko
kernel/drivers/net/wireless/ath/ath.ko
kernel/drivers/bluetooth/ath3k.ko
and my hardware list:

Boot too slow
