All the time things goes well - thanks you people, but from November 2002 there are two bugs: 1) Now ACPI can't read battery information from my batteries: those are SONY 2) Now kernel can't read info about thermal zone - kernel tells me -296 C - I thought, that apsoluttly zero is -273 :)) You guys are really good :) Both thinks worked in ACPI 18112002 or 22112002 now I don't know My system is Debian Woody 3.0r1 here is dump from dmesg: Linux version 2.4.21-pre4 (root@notas) (gcc version 3.0.4) #2 Čt úno 20 16:51:00 CET 2003 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 0000000000100000 - 0000000017fdb000 (usable) BIOS-e820: 0000000017fdb000 - 0000000018000000 (reserved) BIOS-e820: 00000000ffe00000 - 0000000100000000 (reserved) 383MB LOWMEM available.
