..following: "Trying to use devtmpfs (ignore errors)"
This behavior gradually started about a month ago...about twice a week when starting up. Would then fire up and be just fine after a cold boot. Gradually became daily occurrance, and about Monday of this week, refused to boot at all, almost always stopping in the same place, or at "Unable to mount loop file system". The line pertaining to something called Vboxadd always failed.
I was patient. On one occasion, did the breakfast dishes, fed and watered the chickens, picked up the early eggs, fed and watered the rabbits, and had a second cup of coffee. Still sitting there like a lump.
Also, it would not boot the remaster DVD of the same installation (done on May 10, 2011), which had done the hard drive installation and had "passed" media check. That DVD again passed media check, even though it would not boot regularly. When it did, it was not able to read all my data on the hard drive partitions....probably because I'd been doing PCLOS updates quite regularly and programs had changed. Also tried other remastered versions of PCLOS, all of which originally worked, all the way back to 2009. Also a commercial Mepis 2008 live cd (I was getting desperate!), with no luck there either.
Since I built the machine myself two years ago, I took it completely apart back to bare case and motherboard. Reseated the memory, power cables, the video card and USB card (but not the processor...hate that job); put in new floppy, IDE and SATA cables and Cmos battery (Once had a computer that ate one every 3 months!!), used up a can of air (had also been blown out a month ago), reinstalled the DVD drives and hard drives, and hit the power button.
Same old, same old.
By this time, it was Friday afternoon (I'd been doing a lot of experimenting in my spare time over the week.). I was also ticked off beside being desperate.....I keep track of my checking account on this thing, and wanted to be able to use the updated installation. Wasn't going to happen, so wiped the hard drive (500 GB Sata) that PCLOS was on, and tried the May remaster again. No luck; wouldn't boot.
Shut the machine off and went to do evening chores.
When I came back a couple of hours later, since I was going to be starting from scratch, I tried the original download CD from March 2011, which I'd not tried before. It "passed" media check, booted and I installed it so fast it was unbelievable. Worked fine for about an hour before I shut it off and called it a day. This morning, when I tried to boot up, AGAIN the thing stalled out at the "trying to use devtmpfs...." portion of the boot sequence. A cold boot got it going, and I'm using it to type this.
All of which is a really long way to ask: "Am I looking at some kind of hardware failure instead of software?" I am not a specialist in either, just learn enough to get/keep my own computer running and I've reached the end of my string, so to speak.
I might mention that the time and date cannot be kept current. It is 8:15 am, CDT; the computer says it is 10:10 am. Date today is Sept. 3; it says Sept 1. Did the same thing all this week....on the rare times I could get anything to fire, and I reset it twice last night after the new install. This morning it's back to being off. The CMOS battery was packaged, but has been in my possession for two years, so it COULD BE old.
