[Bug 349767] Re: external USB hard drive disconnects

Thu Oct 28 00:56:05 UTC 2010

I am seeing this same issue under 10.10 with kernel 2.6.35-22-generic.
This is running on a standard Sun Ultra 27 Workstation.

Using a SanDisk U3 Titanium USB stick in this case, but it happens with
all my USB hard drives.

Details from syslog follow.
