>BIOS _OSI(Linux) query ignored - щито это такое

What is OSI and how is it used
OSI is an ACPI method provided by the operating system that can be invoked by ACPI BIOS code. It is used by BIOS developers to detect which operating system is running. The method that should be used (cmp. ACPI spec[1], chapter 5.7.2 and 5.7.3) is OS, but for various reasons, OSI is used to identify recent operating systems. The intent of the OSI function is to identify features provided by the OS. For example some BIOSes check for Vista which supports and demands the latest ACPI backlight functions (compare ACPI spec Appendix B). Vendors sometimes update BIOS to use OSI to work around specific oper- ating system problems. This is very dangerous and should always be avoided. Here is an example of how a vendor wrongly fixed his ACPI BIOS implemen- tation trying to work around a Linux bug. It then broke when newer kernels were fixed after the bug got identified: http://bugzilla.kernel.org/show bug.cgi?id=7787

У dmesg как не страннно есть

dmesg --help

Usage: dmesg [options]

(cut)

Supported log levels (priorities): emerg - system is unusable alert - action must be taken immediately crit - critical conditions err - error conditions warn - warning conditions notice - normal but significant condition info - informational debug - debug-level messages

Так вот обращай внимание с какого _уровня_ идут сообщения в dmesg

Хм.. мануал пишет:

-n level

Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, except panic messages, from appearing on the console.

Тоесть мне теперь нужно выставлять # dmesg -n 4 ребутится, и смотреть, с какого уровня ошибки? ладно :)

вроде аутпут точно такой же...
