I set up a suspend-to-disk partition according to dell's instructions using the mks2d.exe tool. this partition is about 532M in size at the start of disk. freebsd is installed in the remaining disk space. 'acpiconf -s 3' results in a "reboot". the systems seems to start suspending and then I am greated with the BIOS boot screen and then freebsd's boot loader starts like it is a fresh boot. 'acpiconf -s 4' results in a BIOS message indicating that it is proceeding to Suspend-To-Disk then shut down. all fine up to the moment when I boot it. The BIOS restores the system mem then apparently launch my session where I left it. however, the screen is garbled with weird colors, different each time. the system is completely unresponsive while the colors start slowly shifting. it doesn't answer a ping or an ssh request. it doesn't answer ARP requests either [1]. I applied the patch procedure to the DSDT outlined here: http://sandcat.nl/~stijn/freebsd/dell.php But this resulted in no visible changes. I then compiled apm support in GENERIC and enabled apmd. though "device apm" is in there, I have the following warning: Jan 17 02:01:11 eek root: /etc/rc: WARNING: /dev/apmctl not found; kernel is missing apm(4) Discarding this message, which I guess is really a bad thing to do, I tested with and without ACPI enabled. The results are pretty much the same: 'apm -Z' results in no noticeable action save for a sys freeze 'apm -z' leads to the same symptoms as 'acpiconf -s 3' Anyone got this beast to suspend (either standby or s-t-d) correctly? Thanks in advance for sharing your experiences/advices/pointers. Cheers. -- [1] if that matters, it has an i830 chipset. -- Saad Kadhi -- [saad@docisland.org] [saad.kadhi@hapsis.fr] [gpg keyid: 19C6C735 http://pgp.mit.edu] [gpg fingerprint: E3A2 D64B 78EC 1E9D 5EB5 14AA F52F 473F 19C6 C735] ---
