I just had the same issue, here's my Controllers. Wireless was switched
on but I was / am running Ethernet connection and it's still working
after the crash, even though Network Manager is showing network
disconnected.
03:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
0c:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN
[Kedron] Network Connection (rev 61)
At this time, I also starte Eclipse and Java crashed. Now my laptop
froze for 20 minutes while the hard drive was going crazy with some io
activity. After about 20 minutes, I could get a console and saw Java was
writing at about 2mb/s. I killed it off and I regained normal desktop
speed. I don't know or see how they are related but they started at the
same time.
