Hello, I've got acpi issues on my laptop - HP 530.
I think it's some detection issue of temperature values as I had this issues when starting the laptop for the first time per day (thus temperature has be to OK). Last lines before reboot: ... softraid0 at root root on sd0a swap on sd0b dump on sd0b acpitz3: Critical temperature, shutting down acpitz3: Critical temperature, shutting down scsibus2 at softraid0: 1 targets ... What is strange is that I get this from time to time ;) I upgraded to most current snapshot and till now no issue but there are strange temperature degrees (acpitzX) in dmesg I think. I had dualboot with NetBSD and IIRC in dmesg I saw some notes like 'ignoring, value is nonsense' (not exact text but the meaning was like this). If I can help somehow, let me know. jirib OpenBSD 4.7-current (GENERIC.MP) #212: Mon Jul 19 23:43:51 MDT 2010 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP cpu0: Intel(R) Core(TM) Duo CPU T2600 @ 2.16GHz ("GenuineIntel" 686-class) 2.17 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,VMX,EST,TM2,xTPR,PDCM real mem = 2138468352 (2039MB) avail mem = 2093481984 (1996MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 12/10/07, BIOS32 rev. 0 @ 0xf0000, SMBIOS rev. 2.4 @ 0xf3abf (23 entries) bios0: vendor Hewlett-Packard version "68MVU Ver.
