dmesg (cat /dev/hdc > hdc)
Can you try booting into your kernel with the following boot parameter added: i8042.nomux=1 Created attachment 131233 [details]
dmesg (cat /dev/hdc > hdc with i8042.nomux=1)
It's seem to be better with "nomux=1" but I still lost sync (see the new dmesg).
There is a bug filed upstream by a user with the same symptoms and the same laptop: http://bugzilla.kernel.org/show_bug.cgi?id=8740 Sorry for the bugspam, but can you test the latest vanilla kernel which is 2.6.23_rc7 as of this writing. I just try with vanilla kernel (2.6.23_rc7) and the problem is worst. For example I lost sync at kdm start (do you want a dmesg from this kernel too?). Thank you for the link I will follow this discussion to, you true, it's seem to be the same problem. I don't think this is an issue of broken hardware because I have seen this problem the first time I try to burn a CD with Gentoo, it was few days after buying this laptop. Please post the output of: cat /proc/bus/input/devices Here are two more kernel boot options you might try: pci=assign-busses pci=routeirq If either of these produces better results, please post the dmesg output for that one. Hello, here my /proc/bus/input/devices cat /proc/bus/input/devices I: Bus=0019 Vendor=0000 Product=0002 Version=0000 N: Name="Power Button (FF)" P: Phys=button_power/button/input0 S: Sysfs=/class/input/input0 H: Handlers=kbd event0 B: EV=3 B: KEY=100000 0 0 0 I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/class/input/input1 H: Handlers=event1 B: EV=21 B: SW=1 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button (CM)" P: Phys=PNP0C0C/button/input0 S: Sysfs=/class/input/input2 H: Handlers=kbd event2 B: EV=3 B: KEY=100000 0 0 0 I: Bus=0011 Vendor=0002 Product=0007 Version=0000 N: Name="SynPS/2 Synaptics TouchPad" P: Phys=isa0060/serio4/input0 S: Sysfs=/class/input/input3 H: Handlers=mouse0 event3 B: EV=b B: KEY=6420 0 70000 0 0 0 0 0 0 0 0 B: ABS=11000003 I: Bus=0011 Vendor=0001 Product=0001 Version=ab41 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/class/input/input4 H: Handlers=kbd event4 B: EV=120013 B: KEY=4 2000000 3802078 f940d001 feffffdf ffefffff ffffffff ffffffff B: MSC=10 B: LED=7 =========================================================== I tried also (kernel 2.6.21-rc7) pci=assign-busses pci=routeirq without success. Still lost sync but seem to be different not better, just different. will track upstream bug I have the same problem here, with Lenovo 3000N100, kernel 2.6.22 I do have thes same problem (perfectly worked around with i8042.nomux=1) and I am following the addressing upstream i8042.nomux=1 works for me like a charm. Thanks a lot, guys! |
