EHCI controller CS5536 hard disk disconnects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello all,


First, apologies if this message is not posted to the right mailing list - please point me to the most appropriate one if needed.
I get a USB disconnect of my external USB HDD about once per day. 
Enabling USB debug in the kernel shows the first error as 'ehci_hcd 
detected XactErr'. It happens only when the drive is idle. For example, 
I had a process writing on the HDD every 3 seconds and the problem did 
not occur for several weeks.
The bad thing is that it reconnects on another device - initialy 
/dev/sdb, it becomes /dev/sdc, which of course breaks quite a few 
things.
Changing the USB cable did nothing and the disk works fine on other 
computers (Windows-based). I thus suspect a power management bug.
Before resorting to disabling power management altogether, I would like 
some advice/insights on what is going on here, and would like to help 
solve this issue with the best efforts I can provide.

Here follows the full dmesg output and the environment.

Hardware: Alix 2d2 board from pcengines.ch - AMD Geode LX CPU and AMD CS5536 USB controller Kernel version: 2.6.32-5custom01-686 based on same-version Debian squeeze kernel + a few minor tweaks to enable USB debug and disable some hardware drivers USB Device: Western Digital My Bok 320GiB directly connected, alone, on one of the two USB ports (other port is unused)
