Booting again with noapic and noapictimer flags give much the same result, except that it doesn't hang and I don't have to keep hitting keys to make the boot continue.
However, my last post was somewhat wrong. The fan *is* running, but at a constant low speed. You can hear it if you put your ear up to the air vents, and feel a breath of warm air. This may be new behavior, but it's far from full speed -- you can hear it rev up in the first few seconds of the boot process. Most importantly, it's not being thermostatically controlled. CPU temperature will get up to 55C, and the fan gets no noisier even when the CPU is quite hot. There are no files named *thermal* in /proc, except the empty /proc/thermal_zone directory: $ cd /proc; $ find . -name '*thermal*' -print ./acpi/thermal_zone $ There are some thermal devices in /sys, and I attach the list as sys_thermal.txt Also, note that the error in /var/log/syslog is still there: Sep 11 20:21:40 nglap kernel: [ 2.379917] ACPI Exception (thermal-0377): AE_OK, No or invalid critical threshold [20080609] ** Attachment added: "sys_thermal.txt" http://launchpadlibrarian.net/17543014/sys_thermal.txt -- thermal.ko fails -> no fan on laptop https://bugs.launchpad.net/bugs/250241 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
