I've just installed the AMD64 version (5.4 RC 3) on my system (Asus A8V Deluxe Motherboard). The install off the CD's went fine, and I was really happy that Freebsd supports the Promise SATA RAID controller (currently have to Sata Disks in RAID 1 Mirror configuration). However, I'm not facing a problem when the system boots. Occasionally, the system locks up just after the following message: May 8 19:34:49 cronus kernel: Timecounter "TSC" frequency 1802318528 Hz quality 800 May 8 19:34:49 cronus kernel: Timecounters tick every 1.000 msec This doesn't always happen; it typically happens once every 3 reboots. Initially I thought it was CD-ROM related since usually the following line loads after the 'Timecounter' ones: May 8 19:34:49 cronus kernel: acd0: DVDR at ata0-master PIO4 When this happens, the system freezes completely; only a hard reset will 'solve' the problem. In trying to search the archives, I've come across some other people with the same problem and the issue seems to be ACPI related. In fact, when I boot Freebsd without ACPI support, this never seems to happen (although it could be coincidence). I've also added the following line to /boot/loader.conf: debug.acpi.disabled="CPU" This seems to have reduced the problem but not eliminated it completely. I've also tried using FreeBSD 5.3 (i.e. stable), but this seems to have the same problem. Any ideas on what the problem could be? If so how should I go about solving it? Should I disable ACPI completely? If so, how should I go about doing this and how will it affect my system? Thanks, Joe
