Bagaimana Reboot Linux Yang Frozen Tanpa Reset

Ini adalah trik bagus yg pernah aq pergunakan sblmnya. Menghindarkan kita dr kerepotan resetting linux yg frozen.

Dibandingkan menekan tombol POWER pd saat crash yg dramatis, sehingga berarti bahwa Anda harus menunggu meskipun sebuah fsck ketika memeriksa disk boot sistem cadangan nantinya. Tahan Alt + Sysreq / PrintScreen, dan tekan REISUB pada gilirannya (sambil terus memegang tombol2 td). Ajaib: komputer anda akan reboot, setelah menghentikan semua program dan sync drive serta unmount.
Ada beberapa hal lain yang ajaib dapat Anda lakukan dengan SysReq, asalkan Anda mo mencr di dokumentasinya. 😛

Ini yg akan terjadi jika Anda mengikuti trik diatas;
What are the 'command' keys?
_
'r' Turns off keyboard raw mode and sets it to XLATE.
'k' Secure Access Key (SAK) Kills all programs on the current virtual console. NOTE: See important comments below in SAK section.
'b' Will immediately reboot the system without syncing or unmounting your disks.
'c' Will perform a kexec reboot in order to take a crashdump.
'o' Will shut your system off (if configured and supported).
's' Will attempt to sync all mounted filesystems.
'u' Will attempt to remount all mounted filesystems read-only.
'p' Will dump the current registers and flags to your console.
't' Will dump a list of current tasks and their information to your console.
'm' Will dump current memory info to your console.
'v' Dumps Voyager SMP processor info to your console.
'0'-'9' Sets the console log level, controlling which kernel messages will be printed to your console. ('0', for example would make it so that only emergency messages like PANICs or OOPSes would make it to your console.)
'f' Will call oom_kill to kill a memory hog process
'e' Send a SIGTERM to all processes, except for init.
'i' Send a SIGKILL to all processes, except for init.
'l' Send a SIGKILL to all processes, INCLUDING init. (Your system will be non-functional after this.)
'h' Will display help ( actually any other key than those listed above will display help. but 'h' is easy to remember :-)

Pilih:
9. Sanely reboot a locked-up box
dan nikmati hasilnya 😛

selesai
