I've experienced hard hangs with a T60, but none so hard that the system
needs to rest. I have no clue to what causes these hangs, but almost every
time, it happened during system configuration of some sort. I haven't tried
acpi=3Doff but ACPI should work fine on these machines.
Regards,
Adrian

Dear All,<br>
<br>
Has anyone seen weird symptoms similar to the following:<br>
<br>
My T60p generally works fine, but after a few hours of use (usually between=
10-30 of uptime), it locks hard, requiring a power-off-reset.<br>
<br>
After the reset, I can get to grub just fine, but the system immediately<br=

hangs (black screen, no activity) at the instant that grub exits. Memtest w=
ill run just fine though, as will Linux but ONLY if I add the acpi=3Doff pa=
rameter.<br>
<br>
Alternatively, allowing the system to "rest" (with or without AC =
charging) for an hour will make it happy again, and it then boots OK.<br>
<br>
There doesn't seem to be anything I can do to end the sulk, other than =
wait (pulling the battery doesn't help). The machine doesn't seem t=
o be significantly warm anywhere.<br>
<br>
I'm using the VESA driver, so it shouldn't be ATI-related.<br>
<br>
The cause of the lockups themselves is unknown - I can't find any corre=
lation, and often I'm doing nothing at all, or just trying to move the =
mouse pointer. Running "nice yes > /dev/null" a few times (to =
generate a hot CPU) doesn't trigger the bug.<br>
<br>
Any ideas would be welcome.<br>
