Hi Darac, I don't think this is related to HW issue, indeed, I'm experiencing this since some time ago on two different machines. All I can have is the following: root@laptop:~# head -20 /var/log/syslog May 31 22:28:59 laptop syslog-ng[1860]: Configuration reload request received, reloading configuration; May 31 22:28:59 laptop syslog-ng[1860]: EOF on control channel, closing connection; May 31 22:29:00 laptop anacron[11394]: Job `cron.daily' terminated May 31 22:29:00 laptop anacron[11394]: Normal exit (1 job run) May 31 22:49:00 laptop -- MARK -- May 31 23:05:40 laptop kernel: [32915.745040] sdc: detected capacity change from 8019509248 to 0 May 31 23:05:52 laptop kernel: [32927.622139] usb 2-1: USB disconnect, device number 8 May 31 23:08:11 laptop kernel: [33066.384097] NVRM: GPU at 0000:01:00.0 has fallen off the bus.
