usbstick fails in Feisty(7.04)

[Jørgen Best]

The usbstick mounts, but when reading data after a short time (5-20s) the usbstick stops functioning (error pops up: can not read file or map, the Konqueror screen gets of the stick gets empty, only about 5-20 MB gets copied). This bug is specific for Feisty 7.04 (updated from a fresh 6.10 installation). Before the same usbstick functioned on 6.10. My laptop, which is still 6.10, functions still OK. I'm pretty confinced that the usbstick is not broken.

Most of the time small files can be read and written.
A temporary workaround is (sometimes) to disable ehci_hcd (with modprobe -r ehci_hcd)

The USB-stick: is a 512 MB Kingston (Kingston DataTraveler2.0 4.80 PQ: 0 ANSI: 0 CCS)

All software is updated to the latest versions.

Additional info: It seems that this problem also occurs at the previous Ubuntu version (6.10 CD) and latest Debian. Don't know why it didn't bother me before...

Further I saw on the internet that Nvidia did have some problems (I've an Epox 8RDA+ motherboard with Nvidia/nforce chipset) with usb. It should possible be related to acpi, or apic. Switched both off in kernel and bios. It didn't help.

Also I 've seen some notes about timer problems (may be related, the clock is very inaccurate) in the kernel and irq's. I don't know how to check that, and if the Ubuntu kernel is patched for nvidia.

I have this exact same problem. I can copy small files but anything of significance even a few jpgs causes this. I cannot even unmount the drive
and most of the files that make it on there are corrupted. My thumb drives used to work no problem, not sure when that changed but this functionality
is now broken. I am dual booting into windows just to write to my thumb drive :(

[Piotr Bukowczyk (piotr-bukowczyk)]

I have similar problem with "Feisty Fawn". When I try to mount "Kingston", my computer (Intel Celeron Processor, about 392 MB of RAM, 8 years old) suddenly suspends and I must reset it to open "Kingston". I didn't have such a problem when I used "Hoary Hedgehog".

[GlenB (glenbirkbeck)]

I have the same problem with an external USB2 Iomega hard disk under feisty. Bulk copying from an NFS share on a different machine causes it to fail in the same way, especially when copying lots of small files.

My setup is AMD based, quite old, based on an AMI BIOS. Onboard USB is v1.1, so this is via a USB2 PCI card (VIA based I think)

It seems to be the same problem reports here - https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/61235 - something to do with caching or some kind of buffer overflow.

Doing a It seems to be the same problem reports here - https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/61235

Using the command "sudo modprobe -r ehci_hcd" before connecting the drive seems to resolve the error but I am not sure about how it has affected speed. I havent one any time trials, but left it copying data yesterday and it took about 12 hours to do 60GB of data, which, by my (dubious) reckoning, works out around 11Mb per sec

check this one out: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/25931

I had the same problem. I got a message HAL failed to initialize. At the same time my external HD couldnt be found. After changing CONCURRENCY in /etc/init.d/rc back to none from shell my problem was solved.

Hope this works for you guys.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Jørgen Best (jorgen-for-business01022004)]

I'm Sorry.
I'm trying to help you but the alpha 4 release states that it uses the
2.6.26 kernel so I can't test the 2.6.27 Kernel. Also nothing was
available as a package (I use the 8.04 stable release).

[Jørgen Best (jorgen-for-business01022004)]

It seems that this bug is fixed in 8.10 Alpha 5 (2.6.27).
I tried coping three times with big files and it didn't fail (because of
the random character it is probably fixed, not sure)

I was not able to test with 2.6.26 because the Alpha 4 iso was removed
of the Ubuntu site.

[Leann Ogasawara (leannogasawara)]

Setting this to "Fix Released" based on the decision to stick with the 2.6.27 kernel for Intrepid - https://lists.ubuntu.com/archives/kernel-team/2008-September/003107.html

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
