** Description changed:
- This bug report is a follow-up to bug 1328984, describing a successful
- attempt to replicate that bug on another hardware. As advised, I am
- opening a new bug to avoid mixing information related to two hardware
- configurations.
-
- Conditions triggering this bug:
- As the original bug (1328984) was encountered on machines that are production
servers, I attempted to replicate in on another machine that could be entirely
devoted to testing this issue. I equipped this computer with the same USB3
hardware as the servers, that is the HighPoint RocketU 1144C USB 3.0 controller
and Areca ARC-5040 USB 3.0 RAID enclosure connected to it. I was able to
replicate the problem with ease, provided that all three following conditions
were met:
-
+ With a Dell Vostro 430, the HighPoint RocketU 1144C USB 3.0 controller, Areca
ARC-5040 USB 3.0 RAID enclosure connected to it, and the following conditions
are met:
1. System booted kernel 3.2.0-64,
2. HighPoint RocketU 1144C controller was installed,
3. Areca ARC-5040 was connected to that controller.
+
+ An error loop during boot contains the following messages:
+ [ 34.084469] usb 8-1: reset SuperSpeed USB device number 2 using xhci_hcd
+ [ 34.101825] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with
disabled ep ffff88042102e000
+ [ 34.101918] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with
disabled ep ffff88042102e040
+ This continues for about 18 minutes, after which the filesystem on the Areca
drive is mounted, and boot process continues successfully, as if nothing had
happened. Afterwards the affected drive works seemingly fine, although I
experienced some system instability, causing a total system freeze. At this
point I am not sure if this instability is related to the problem at hand.
+
+ I've attached a file generated by apport-cli -f -p linux --save
+ filename.apport .
The problem did not appear if I booted an older kernel (e.g. 3.2.0-63),
or if Areca enclosure was not attached, or if it was attached using
another interface (USB2 or eSATA). The problem was also absent if I
replaced the Areca enclosure with another USB3 device (a flash drive).
The test machine's motherboard did not have a built-in USB3 controller,
but I performed an additional test on yet another computer, equipped
with a NEC USB3 controller. That test was done with kernel 3.2.0-64 and
the Areca enclosure, and did not replicate the problem. Thus I assume
that it is the combination of the RocketU controller and a specific USB3
- device that triggers kernel regression. In the original bug report
- (1328984) Bard Hemmer reported that he encountered a similar trouble
- with Western Digital My Passport 2TB USB 3.0 external drive. I happen
- to own this exact model, and I intend to test it as soon as possible.
-
- Symptoms:
- The symptoms on the test machine are somewhat different than those occurring
on the production servers. The error loop during boot contains the following
messages:
- [ 34.084469] usb 8-1: reset SuperSpeed USB device number 2 using xhci_hcd
- [ 34.101825] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with
disabled ep ffff88042102e000
- [ 34.101918] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with
disabled ep ffff88042102e040
- This continues for about 18 minutes, after which the filesystem on the Areca
drive is mounted, and boot process continues successfully, as if nothing had
happened. Afterwards the affected drive works seemingly fine, although I
experienced some system instability, causing a total system freeze. At this
point I am not sure if this instability is related to the problem at hand.
+ device that triggers kernel regression.
Similar effects happen if Areca enclosure is hot-plugged to the working
system. In such a case OS boots fine (as the enclosure is absent during
boot). After plugging the Areca, the drive is unavailable for 18
minutes, during which time numerous errors as above are logged. After 18
minutes elapse, drive is mounted and behaves normally.
-
- Hardware:
- Dell Vostro 430
- CPU: Intel Core i7-860
- RAM: 16GB DDR3 unbuffered non-ECC
- Add-on card: HighPoint RocketU 1144C 4-Port USB 3.0 PCIe 2.0 x4 HBA
-
- Software:
- Ubuntu 3.2.0-64.97-generic 3.2.59 x86_64
-
- Note about apport collection:
- Due to problems described in bug 1328984, relevant to this setup as well, I
am unable to run apport tools to submit system information. For this reason, I
am attaching a file generated by apport-cli -f -p linux --save filename.apport
