We have exactly the same problem here https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/83544
Also, I tried to recompile the kernel with a custom DSDT (I added the path of the dsdt.h in the menuconfig). There was no error at compilation but after boot, the DSDT doesn't seem to work (I think the kernel hasn't been compiled with the dsdt.) -- Custom DSDT doesnt appear to work with initrd in 2.6.20-8-generic kernel https://launchpad.net/bugs/85435 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
