Hi Erich,
Well, there isn't much I can tell you. The box in question resides 8 hours away. It worked for approximately 6 months, then I got the call from that office to tell me it wouldn't boot. They sent the CF back to me and I poked around it a little. Not much to see, it simply wouldn't boot. So I assumed a bad CF, rebuilt their system on a new card and sent it back to them. They plugged the new card into the box and it has worked properly since mid-May, failing just before Christmas. Same symptoms. This time I had them send the whole box back to me. I don't see anything wrong with the box. However, as this happens so rarely, it could really be anything. Flakey power supply, two bad CF's in a row (possible if not very likely)
I had symptoms like that on BiWin CF's. I have a number of those deployed and I usually check them by writing the entire CF. If they report a problem back they go...
It might be the CF adapter, yu did not change that one did you?
IO at boot is conrtolled by BIOS, not a linux driver, so this may be a difference too.
, maybe even an unwelcome visitor... who knows.
Possible, or else having the CF mounted at a full back up? you could write an md5sum of the contents and check regularly.
When it takes 6 or 7 months to repeat the failure, it's difficult to efficiently trouble shoot this problem. ;-)
Unfortunately, the symptoms aren't much to go on! It worked one day, but not the next! I'm going to use a twin machine to replace this one, with a new (same model PC-Engines adapter board - type 1C) CF adapter and CF card. If this one fails later this year I'll be back where I started... pretty much nowhere.
I just don't understand what could wipe the boot area twice in a row, but leave the rest of the card untouched... power spikes, flakey IDE cable, nothing really adds up to this result. My only idea revolves around the possibility that the BIOS is not auto-detecting the card properly. I've talked to Lexar,
OK so you are using Lexar, better than BiWin IMHO.
Good Luck
Erich
