1) Does the system go out from this state after some time or you have to |
| 23 |
cold reset it? |
| 24 |
2) What happens if you put PORTAGE_NICENESS=19, MAKEOPTS of "-j2 -l1" ? |
| 25 |
l5 (small "L", not the number "one"), means "loadavg=<1" If loadavg goes |
| 26 |
up to 1 make waits this level to drop before continuing its job |
| 27 |
3) Is DMA enabled for your HDD(s)? (hdparm -d1 /dev/xxx)? |
| 28 |
4) Have you done any overclocking? |
