I got a report from someone who experienced lockups when using |
| 2 |
gentoo-embedded built system (2.6.14-hardened-r1) |
| 3 |
|
| 4 |
He managed to reproduce it on 2 different computers by doing this: |
| 5 |
|
| 6 |
install openssh |
| 7 |
|
| 8 |
get an ip address using dhcpcd |
| 9 |
|
| 10 |
# create a network stream |
| 11 |
ssh root@otherbox "dd if=/dev/urandom" > /dev/null |
| 12 |
|
| 13 |
wait a while |
| 14 |
read something from cdrom. |
| 15 |
|
| 16 |
Now the box locks up: |

> Box locked up - no kernel panic, no messages, keyboard's locked up - |

> no more activity on the net interface lights. |

When he uses dropbear & udhcpcd it works? |

I have not been able to reproduce it. |

I wonder if anyone here have experienced something similar? |
| 30 |
|
| 31 |
Only lockups I have experienced have been lockups after some time of no |
| 32 |
activity at all. Booting with "noacpi" fixes that. (but i still dont |
| 33 |
know why it happens) |

The kernel config used are here: |
