Linux kernel bug tracking system: http://bugzilla.kernel.org/ When attaching binary files or large test files (dmesg logs, ACPI table dumps, etc), don't insert them as comments; make them attachments instead. Please do not compress attachments. Install ACPI table dump utilities: On Debian or Ubuntu: $ sudo apt-get install acpidump iasl Otherwise, build the "pmtools" package from source: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ Collecting ACPI tables: $ sudo acpidump > acpidump.asc $ acpixtract DSDT < acpidump.asc > DSDT.aml $ iasl -d DSDT.aml Attach "acpidump.asc" and "DSDT.dsl" to the bugzilla. Collecting PNP debug information: Build kernel with "CONFIG_PNP_DEBUG=y". Boot new kernel. $ dmesg -s999999 > dmesg Attach "dmesg" to the bugzilla. Collecting PNP device information: If "lspnp" is available: $ lspnp -v Or: $ grep . /sys/bus/pnp/devices/*/*
