Принесли практически новый сабж. После экспериментов электриков вышел из строя как БП, так и роутер. БП я починил, а вот с роутером беда. С периодичностью в 15сек происходит перезагрузка. Подключил Путю и вот что увидел:

Пробовал шаманство через tftpd - даже не пытается.
Я не совсем понимаю, что именно сломалось: boot-загрузчик вроде бы живой, если он пытается загрузить ядро, в то же время не дает паузу перед этим?
Или залита была какая-то хитрая прошивка, которая заодно и свой загрузчик зашила без поддержки Recovery Mode?
В принципе, на ПК присутствует LPT-порт, и можно собрать JTAG-адаптер, но для прошивки нужен полный дамп с флеш ром (если я правильно понимаю всю продцедуру).
