[Bug 349767] Re: external USB hard drive disconnects

Thu Oct 28 08:04:47 UTC 2010

I have run into this bug as well, but could make the following observations:
 (a) this problem does not appear if you use a kernel <= 2.6.31 (that's actually my current "solution" - running lucid using the  2.6.31 kernel)
 (b) this bug strikes on my IBM/Lenovo X41(Intel 82801 FB/FBM/FR/FW/FRM (ICH6 Family) USB chipset) as well as on my company's Dell Optiplex 745 (Intel 82801H (ICH8 Family) USB chipset). My company's Lenovo X200 featuring an Intel ICH9 chipset is not affected.
 (c) its quite safe to use "older" USB disks such as a Maxtor 320GB external drive, but newer drives are highly sensitive to this bug.

Maybe there is some feature for external USB drives which got supported
in 2.6.32 triggering this bug on drives supporting it.
