Suspend worked regardless of video mode, although X11 would need "flicking" to a virtual console to get the mouse pointer back. Everything seemed to function fine, although I did experience random reboots periodically when the CPU was hot. Under 5.0-CURRENT/RELEASE the default behaviour to use ACPI appears to cause problems with thermal control, and causes random panics. On several occasions running ACPI I have seen warnings of the CPU reaching 99deg C, followed by an immediate ungraceful power off. Suspending does not work properly when using ACPI, and attempting to use it usually results in a system hang. I have attributed this to be a buggy ACPI BIOS implementation in this machine, but would be happy to help anyone who thinks they can fix these problems. Switching to APM under 5.0-CURRENT seems to resolve most of these issues, with the thermal fan functioning more as you would expect. The case still gets quite warm, but I have not observed any heat related incidents so far. However suspend will NOT work if X11 is running without first switching to a vty. Attempting to suspend in X11 will result in the console becoming unresponsive, and causing an incessant beep when attempting to switch to a vty, requiring a reboot. Other than a slight reduction in power management functionality (ie. suspending in X no longer works), everything else seems to work fine. A couple of other random things I have observed/found: o Particularly bad "crashes" can leave the filesystem in such a state that continuing without a foreground fsck will cause a kernel panic when the effected files are accessed. I had a /var that exhibited this problem, only solution to panic was single user mode boot and 'fsck -y' (no tracelog sorry) o Using DHCP will not work with a PCMCIA network card if you also run DHCP on a fixed interface because dhclient is already running and pccard_ether (called by devd) will not attempt to kill it first. (This is not a new problem) o omshell(1) has now been included, however OMAPI does not appear to be functional within dhclient(8) at this time. o The dhclient(8) manpage incorrectly lists omshell(1) as omshell(8) when detailing the '-w' flag o There is no way to tell smbutil/smbfs which interface to use for NetBIOS broadcasts if you have more than one interface. Downing the undesired interfaces results in errors. -- Seeya...Q -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _____ / Quinton Dolan q_dolan@yahoo.com.au __ __/ / / __/ / / / __ / _/ / / Gold Coast, QLD, Australia __/ __/ __/ ____/ / - / Ph: +61 419 729 806 _______ / _\
