Hello, I'm running a dual P3 IBM eserver x330 with FreeBSD 6.0-RELEASE. A ran into two problems after my initial installation that were both resolved by disabling ACPI. The first problem I experienced was an odd hang after this portion of the boot: ad4: 152627MB <WDC WD1600JD-00GBB0 02.05D02> at ata2-master SATA150 ad6: 152627MB <WDC WD1600JD-00GBB0 02.05D02> at ata3-master SATA150 It would sit there (apparently) idle for approximately 2 minutes and then proceed to boot normally. After disabling ACPI, everything booted very quickly. I started experiencing the second problem after I compiled in SMP support. The problem was that I was receiving the following in /var/log/messages whenever I would run 'top' or 'ps'. Dec 14 20:31:56 foo kernel: calcru: negative runtime of -7248805 usec for pid 46 (swi4: clock sio) Dec 14 20:31:56 foo kernel: calcru: negative runtime of -7248805 usec for pid 46 (swi4: clock sio) Once I disabled ACPI the messages no longer showed up. Is there a known problem or bug in this platform that would explain this behavior? I did some searching through the mail archives, but I couldn't find anything similar. If anyone is interested, I can follow-up with more information such as the dmesg output from 'boot -v'. Regards, Brett Gianpetro
