Copying A Large Amount Of Files VIA Samba Disables CD-Rom Drives

[Jeremy LaCroix]

Binary package hint: samba

On my system I have a DVDRW drive and a CDRW drive, master and slave configuration.

Both drives work fine, copying files, reading discs all work as expected.

If I copy a large amount of files via Samba, the drives stop working. No matter which drive I use, if I insert a CD or DVD, it will tell me that there is no media when I try to mount it. If I reboot, all returns to normal until the next time I do a large copy (probably over 3gb) and then the drives stop working again. This is strange because I'm not even using the drives when this happens.

This all worked fine before Hardy.

Steps to reproduce:
1.) Copy a large amount of data to affected machine from Samba via network
2.) Try to mount a CD or DVD
3.) Will not mount
4.) Reboot
5.) Drives start working again.

This sounds like a kernel issue. If possible can you attach the output of dmesg

Thanks

It just happened again just now.

Here is a fresh copy of dmesg right after this happened.

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.

[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.
