My server went down yesterday and on my next restart I was getting an error that said kernel panic - not syncing vfs unable to mount root fs on unknown-block(0 0), I did some quick research and sounded like a bad USB could be the issue so I created a new one.
After trying to boot from the new USB I started getting a new error message: rip: 0010:panic+0x1e3/0x224 So I did some more research which lead me to do a memtest. When running that, I got 20 errors on Test 4, see https://imgur.com/Bdbe9au.jpg
Today I went out got a new stick of ram, put it in and it started. I decided to see if the error was the old Ram so I reinstalled it and tried to start again. And I got the same error message: rip: 0010:panic+0x1e3/0x224 . So looks like bad ram let me pull it and start up again without it.
On the next start, I get the same error message: rip: 0010:panic+0x1e3/0x224 with only the new stick in. Now I feel like a dummy.
So I shutdown and run the memtest on just the new RAM, and I get 16 errors this time, on the same test #4. So I shutdown, pulled the ram, cleaned the pins reseated the RAM and tried to boot again, same error message: rip: 0010:panic+0x1e3/0x224
Now I am questioning why I had to try that RAM, WHY? So I try a new USB again and the server boots up no problem. I am happy its back on, but is that RAM stick bad or was the problem the USB?
So my question is, could the bad USB be the reason I was failing the Memtest? Or is that RAM bad? If so why did I get errors on the new stick?
Bad Ram or Just a Bad Usb?
