My T21 works well with S3, S1. > Could you please narrow down the issue ! > --Luming After several google searches and reading up on posts by others abt similar problems with ACPI, I was leaning towards the theory that it's got something to do with the Intel 855 graphics adapter on both my Fujitsu and Mads's ASUS. I read on another post that the graphics card had issues with ACPI (that one wasn't Intel 855).. But after looking at the syslog, this doesn't seem to be the problem: there was a message that said it was looking for "Module char-major-10-134" (the APM module) when it resumed -- I put in an alias to set this to off and that error went away. I also removed all the modules before I suspended and that reduced the number of errors I get when it resumes. But these are the remaining messages from syslog: Dec 23 02:22:13 variance kernel: Back to C!

Dec 23 02:22:13 variance kernel: drivers/usb/host/uhci-hcd.c: 1860: host controller halted. very bad So looks like there's some problem with the uhci-hcd controller? I googled and it's a recognized bug: http://bugzilla.kernel.org/show_bug.cgi?id=1373 The workaround suggested is to rmmod the uhci-hcd module .. I have it built into the kernel so maybe I need to recompile this as a module... However, the others have been able to resume, just that the USB devices don't work.. mine doesn't resume at all.. could this have to do with the following error above: cpufreq: resume failed in ->setpolicy/target step on CPU 0 Should I uncheck the CONFIG_X86_ACPI_CPUFREQ=y option in the kernel config? Btw, the thermal_zone directory in /proc/acpi is empty.. I did enable it in the kernel configure .. the same goes for fan/ - it's also empty.
