Has anything changed WRT ACPI > use on your system in the last week? Nate committed the ACPI blacklist actually I am testing on two hosts that had been running 4-STABLE before or nothing at all.

If this really is the problem this should be fixed soon. No ACPI at home too on my router... should not update I guess... *ARGL* someone (most likely me) must have turned the machine off before leaving the office to save it a night of endless boot cycles. Will test tomorrow morning. PS: the (funny) thing is that serial console used to work two days ago but the kernel paniced. I then updated srces and serial console stopped working but the kernels now boot but panic somewhere later forcing a reboot but I cannot see that - must be around if_tx gets used for pppoe (I guess) :( Going to build a pre-20040702 and latest HEAD over night and will see what happens tomorrow morning. Thanks for today. -- Bjoern A. Zeeb bzeeb at Zabbadoz dot NeT
