Message-ID: <j3m0fu$9nu$1@dough.gmane.org> (raw)
Имеем сизиф с 3.0.1-std-def-alt1
Пытаюсь через dd на фэшку записать образы с новыми Симпли и КДесктоп (на
разные флэшки). Через пару минут процесса в dmesg можно обнаружить
sd 8:0:0:0: [sdj] Asking for cache data failed
sd 8:0:0:0: [sdj] Assuming drive cache: write through
sd 8:0:0:0: [sdj] Attached SCSI removable disk

и так далее.
При этом все тормозит. Но вроде дальше не падает, и флэшка записывается
нормально. Хотя панели и апплеты КДЕ замерзли и не очнулись.
