I set up a new AMD computer (moved disk from previous Intel |
4 |
computer). After some struggles with bios settings, I got it to boot |
5 |
properly and updated for the new hardware. All seemed fine, but then it |
6 |
started "crashing" when left alone. From Googling, it seems that it has |
7 |
something to do with the bios powering down drives that aren't in use, |
8 |
but then not being able to power them back up. |
9 |
|
10 |
When it "crashes" (goes into a coma?), I have to use the power button to |
11 |
turn it off and then back on. As it starts up, the root partition is |
12 |
clean, but home has to be recovered - which seems to indicate that it is |
13 |
indeed an issue with the mobo/bios turning off the root drive. |
14 |
|
15 |
I found a Linux site that suggested this line in dmesg as a symptom: |
16 |
|
17 |
> [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) |
18 |
|

The solution was to turn of C-states in the bios. I forget the exact |
20 |
wording right now, but I could not find it in my bios. I tried to turn off |
21 |
everything that seemed related to power saving, but several did not have |
22 |
an "off" option. So, I am still getting the error. |
23 |
|
24 |
For now, I set up a cron job to move a file from /root to /tmp every 15 |
25 |
minutes. This seems to work, but it is obviously not a long term |
26 |
solution. |
27 |
|
28 |
I checked for a bios update, but there was not one available. |
29 |
|
30 |
Has anyone else experienced this? Is there maybe a /sys/ or /proc/ file |
31 |
I can tweak to avoid bios powering things off? |
32 |
|
33 |
Thanks. |
