1. When you kernel compilation failure ... The most obvious mistake is not the normal boot ..
This time you need to pay attention to the error message is ... what ...
Serious error occurs if prompted panic ...
2. In the boot process ... you should have noticed that in the last 9 seconds of the thing, too ....
(Do not say you do not know ... If that do not know .. please send your resume FreeBSD, and then carefully look at him concluded a)
Normally, we usually enter directly from boot to FreeBSD right away ...
This time, you need to press the enter key in addition to any other than the key, I used to press space key Rights ...@
3. Then there will be a prompt ... As is valid and ... I forgot ....
(I can not stopped re-opened this page to see it .. maybe ... a chance .. .. I will see and be added)
You can look at the prompt, enter? Can view all in this mode can execute instructions
4. With the old kernel boot
a.lsmod see that the kernel used
b.unload to not boot (properly be said to be current) kernel unload
c.ls to see what files are now
d.load kernel.GENERIC load the original default GENERIC kernel FreeBSD
e.boot continue to boot
5. To enter into / usr/src/sys/i386/conf amend the wrong place before the kernel, recompile After correction
a. Path: / usr/src/sys/i386/conf
Command: config OHAHA
/ / OHAHA kernel for my name, kernel name used uppercase hostname
b. Path: / usr / src / sys / compile
Command: make depend all install
/ / This is the lazy approach ... is equivalent to make depend with make and make install
c.sync; sync; sync; reboot
Restart the system, test to see whether the error correction
In fact, you can not sync the next ... this is not superstitious ... but since the pain does not ... then easily add it ..@@"
6. Let us pray about .... this time .... you can reboot ......-___-||
