Asus ACPI: Error reading display status Jan 19
Asus ACPI: Error reading LCD

Sometimes I have some problems connecting to other systems using 10Mbit/s half-duplex NIC's. First I thought that there might be a conflict with the USB2.0 mouse - but I sporadically observed the problem even without the mouse.

The second guess was the autosensing function of the NIC. I tried to set speed and mode manually using ethtool. Even though ethtool reports correct speed and mode it is not possible to establish a connection.

Disabling, restarting or unloading the driver does not solve the problem (ifup, rcnetwork restart, modprobe -r 8139too).

Testing several configurations of the network interface I discovered, that the NIC works well whenever I booted Linux after I first switched Win-XP into suspend-mode. So I suppose that Windows initiallizes the NIC in an other way than Linux does. Switching Windows to suspend-mode does not change this setting so that Linux can use the NIC correctly. In this way the NIC can bes used without restrictions.

I found another good howto for the installation and configuration process at http://www.rage3d.com/content/articles/atilinuxhowto/Linux_ATI.pdf.

1. download the drivers
2. installation of kernel-source, make , gcc
3. as root: # rpm -Uhv fglrx*.rpm
4. cd /usr/src/linux
5. rm .config
6. make cloneconfig
7. make prepare-all (only for kernel-source >= 2.6.5-7.75)
8. as root: # rpm -Uhv km_fglrx*.rpm
9. cd /usr/src/kernel-modules/fglrx
10. KERNEL_SOURCE=/usr/src/linux make modules
11. KERNEL_SOURCE=/usr/src/linux make install
12. depmod -a
13. copy /usr/lib/fglrx/lib/libGL.so.1 and /usr/lib/fglrx/lib/libGL.so.1.2 to /usr/X11R6/lib
14. configure ATI-driver as root with: # fglrxconfig NOTE: Don`t use SAX to enable 3D support ! fglrxconfig writes an XF86Config-4 file
15. save a copy of the original XF86Config file and replace it with the one generated above.
16. reboot; first I thougt that a restart of X is enough but I found that after a reboot the driver worked well. Drawback: after the installation standby and suspend did not work any more. The system hangs.

ACPI: Processor [CPU1] (supports C1 C2 C3, 8 throttling states)

# cat /proc/acpi/processor/CPU1/power

active state:            C2
default state:           C1
bus master activity:     ffffffff
states:
    C1:                  promotion[C2] demotion[--] latency[000] usage[00852920]
   *C2:                  promotion[C3] demotion[C1] latency[099] usage[14043474]
    C3:                  promotion[--] demotion[C2] latency[999] usage[00000000]

Anyhow, the notebook runs for more than 4 hours without power supply - using it under office conditions.

Version 0.2
After I installed the kernel 2.6.9 I had problems after standby-resume und suspend-resume. Everything works well except that it is not possible to switch to standby- or suspend-mode again. Furthermore, the kpowersave-icon is not visible. I discovered that after typing

killall -SIGHUP powersaved
rcpowersaved restart

everything works well again.

Version 0.1
USB-Problems: dmesg shows the following problem:

ehci_hcd: probe of 0000:00:1d.7 failed with error -95
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x50

After a while of use my USB-mouse is out of function. I am not able to reanimate it. The only way is a reboot.

Version 0.2
After I installed the kernel 2.6.9 dmesg shows

In Line 3 a BIOS bug is reported, but the kernel continues to initiallize the usb. With the 2.6.9 kernel the function of the usb-mouse is perfect.
