Last successful cvsup was May 20th. After cvsup today, and a "build-world" I see something _similar_ to below when trying to boot. --------------------------- Can't work out which disk we are booting from. Guessed BIOS device 0xffffffff not found by probes defaulting to disk0: panic: free: guard1 fail @ 0x517c4 from [line folded for mail] /usr/src/sys/boot/i386/loader/../../common/module.c:957 --------------------------- (I say similar, becuase the above text is actually copied from another web post. But mine is similar. If *my* text is needed I can reproduce the issue to obtain it.) I did a google or two and found nothing of use. Maybe I am using the wrong keywords. If I bring the machine up in Safe Mode or with ACPI Disabled everything is fine (I am writting this from the machine in question). Nothing else has changed other than a cvsup and build-world (meaning no hardware/BIOS changes). Anything I can provide to help diagnose this? I am running FreeBSD 6.1-STABLE #0: Wed May 31 12:05:21 CDT 2006 on a Dell Inspiron 5100. I have cvsupped back to 05-15-2006, which is before my last known good cvsup and things still fail. So now I am wondering if some hardware has failed. Any ideas? -- Regards, Eric
