<li><p>Система не загружается корректно. Она может спонтанно перезагружаться на каком-то моменте или зависать (например на каком-то значке экрана загрузки). В случае зависания попробуйте нажать <span class="key">ALT</span> <span class="key">SysReq</span> <span class="key">D</span>.</p></li>
<li><p>Система или какое-то устройство не работает нормально. Например если она работает очень медленно, появляются ошибки, или что-то вообще не работает. Если какое-то устройство вообще не работает первое что нужно проверить это поддерживает ли его Haiku в данный момент (например спросить в списке рассылки или на форуме).</p></li>
</ul>
<p>Заметьте, что хотя только последний пункт указывает на проблему связанную с оборудованием, все остальные симптомы могут также быть вызваны ошибкой в драйвере оборудования. Если вы подозреваете, что какое-то устройство или его драйвер могут быть как-то связаны с наблюдаемой проблемой, то проверьте изменится что-либо после отключения устройства или удаления его драйвера. Например если вы подозреваете Wifi, то вы можете найти опцию в BIOS для его отключения. Если же такой опции нет, то вы можете удалить соответствующий Wifi драйвер (из папки <span class="path">/boot/system/add-ons/kernel/drivers/bin</span>).</p>
<p>Note that while only the last point seems to indicate hardware relation, all the other symptoms could be caused by a bug in a hardware driver as well. If you have a suspicion what piece of hardware or corresponding driver might have to do with the problem, check whether removing/disabling the hardware or the driver makes a difference. For example, if you suspect Wifi you may find that your BIOS has an option to disable it. Or if not, you could blacklist the responsible Wifi driver from your Haiku installation (see <a href="../../../userguide/en/bootloader.html">Boot Loader</a>).</p>

<p><b>This is the preferred method for gaining information from a non-booting system.</b><br />
The syslog (short for system log) contains valuable information about what has happened in your system, including the output of KDL sessions. It's usually a good idea to attach it to the kernel related Trac ticket. The syslog is written to the file <span class="path">/boot/common/var/log/syslog</span>. Since writing to a file requires a working system, the most recent output might not have made it to the syslog when a kernel problem occurs (particularly on spontaneous reboots or uncontinuable KDL sessions).</p>
<p>The option <span class="menu">Enable debug syslog</span> in the boot loader's <span class="menu">Debug menu</span> makes the syslog somewhat persistent in memory. By default the option is enabled. "Somewhat persistent" means that it survives a reset and will still be accessible when you enter the boot loader menu directly afterwards. Booting an operating system (Haiku definitely, others likely) destroys the information, though. So you have to enter the boot loader menu by holding down <span class="key">SHIFT</span> while booting.<br />
In the boot loader's <span class="menu">Debug menu</span> you should now find the entries <span class="menu">Display syslog from previous session</span> and <span class="menu">Save syslog from previous session</span>. The former displays the syslog on screen, the latter allows you to save it as a file to disk. Note that at the moment only FAT32 volumes are supported for saving the file. If you want to use a USB stick, but have plugged it in too late so that it isn't recognized yet, you can reset the machine and re-enter the boot loader menu. But again: Don't accidentally boot any operating system or the data will be lost.</p>
