Would you possible have a work around for this problem? TIA Ok, gotta throw one out for some help. Long story short is, I have a laptop that I just purchased for a client, has nvidia and runs perfect with Ubuntu Gutsy except for 1 little (kinda huge) problem. The bios that ships with most laptops lately , COMPLETELY SUCK (I hate phoenix). There is absolutely NOTHING in the bios to help control acpi or apic. My problem is that I have NO SOUND unless I boot with the kernel boot option of "acpi=off", then all works perfect except I have no battery monitoring, which on a laptop is pretty huge, if this was a desktop, it would be no biggie (not sure if it would affect ups monitoring). I notice that I have ERR=1 from /proc/interrupts. I have tried all sorts of combinations of boot options, including "noapic nolapic pnpbios=off" and I forget the rest I've tried, nothing works except for turning off acpi completely and then no battery monitor. I've looked into apm but can't recompile the kernel because then all the other "restricted" packages won't work with the custom kernel and that option is basically a pain in the ass. I feel this is probably related to the ERR=1 from interrupts but I can't seem to clear this, it only gets worse with other boot options I've tried. Does anyone know how to reroute irq's or make them behave better (yes I've tried pci=routeirq)? Has anyone else had this problem and found a solution? Currently my work around is 2 grub boot stanza's, one is to have sound which runs "acpi=off" and the other is to have no sound and everything else works (battery monitor), without the "acpi=off" option. Any help please? TIA
