I noticed that on my Thinkpad T21 an asus_acpi module is being loaded (I see it in lsmod output). As it (probably, I am not 100% sure) contains functions specific to Asus notebooks (and not IBM's), should it be running? I checked initrd and seems to me that ACPI module loading stuff is reather crude (just tries to modprobe every acpi kernel module, without any checks - but, maybe this is the only possible way)? Not that removing asus_acpi helps with my standby problems :-) Piotr Gawrysiak PS. And just for completeness and as a reminder, 'couse I asked it before here :-) - I am still fighting with suspend and standby on this notebook. Anyone managed to do it? For me APM suspend does not work at all (notebook does not want to suspend after pressing Fn-F4) and while using ACPI echo 3 > /proc/acpi/sleep breaks sound module (after resume AC97 driver complains loudly and stops working) and network (e100 - at first seems to be working, but after ~20-30 minutes drops connection and I have to remove it, and modprobe again - btw. this helps only for the next 30 minutes and afterwards the procedure has to be repeated :-) If the notebook has not been suspended both sound&network work well). The ACPI suspend is also strange - I can wake up computer only with power button, not Fn key... Anyone has any hints? In fact it seems to me that 2.6 kernel in its current version is not really mature for laptop use, and I am thinking about downgrading...
