| 8 | The following bugs in Linux kernels prevent them from executing
|
|---|
| 9 | correctly in <ph conkeyref="vbox-conkeyref-phrases/product-name"/>, causing VM boot crashes:

|

| 14 | The Linux kernel version 2.6.18, and some 2.6.17 versions,
|
|---|
| 15 | introduced a race condition that can cause boot crashes in
|
|---|
| 16 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/>. Please use a kernel version 2.6.19 or later.

|

| 21 | With hardware virtualization and the I/O APIC enabled,
|
|---|
| 22 | kernels before 2.6.24-rc6 may panic on boot with the
|
|---|
| 23 | following message:
|
|---|
| 24 | </p>
|
|---|
| 25 | <pre xml:space="preserve">Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with
|
|---|
| 26 | apic=debug and send a report. Then try booting with the 'noapic' option</pre>
|
|---|
| 27 | <p>
|
|---|
| 28 | If you see this message, either disable hardware
|
|---|
| 29 | virtualization or the I/O APIC as described in
|
|---|
| 30 | <xref href="settings-system.dita">System Settings</xref>, or upgrade the guest to
|
|---|
| 31 | a newer kernel.
