Just finished an install of Ubuntu 8.04 Hardy Heron, and I'm seeing this same issue. The kernel is logging the following every six seconds:
Apr 27 21:28:58 sunshine kernel: [ 1353.176717] ACPI: Unable to turn cooling device [d9dcff18] 'on' This is with kernel 2.6.24-16-generic. No updates have been released for Hardy as of this writing. (First time I've tried Linux on this hardware, so I don't know if issue presents on this hardware with older software.) Hardware is an HP Pavilion a635w desktop, which uses an Asus A7V8X-LA motherboard with a VIA KM400 chipset. I've got the latest BIOS from HP installed. Power supply, chassis, and CPU fan are all spinning. If I rmmod the "thermal" module, log messages cease; if I insmod it again they start up again. No match for "PBLK" in any of the /var/log/{dmesg,messages,kern.log} files. In an eyeball review, nothing leaps out at me for an obvious cause, but I'm no expert at ACPI. I'll attach dmesg and dmidecode output. If there's anything more I can do to assist, please let me know. ** Attachment added: "dmesg output" http://launchpadlibrarian.net/13975649/dmesg.out -- ACPI: Unable to turn cooling... https://bugs.launchpad.net/bugs/63550 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
