View Full Version : kernel BUG in NFS4 (introduced in 3.0.101-0.47.50-pae)

after rebooting into the new kernel our machine stops hard whenever someone logs in (which causes autofs to mount the user's homedir).

I worked around the problem by downgrading to NFS3, but this might want to be fixed :)

none of the x64 machines crashed (yet), so this problem might be confined to the i586 version.

Forums are not an official support channel, if you're seeing a bug like this I advise you raise a Service Request.

This looks like the same issue I reported to SUSE three days ago. I saw it in SLED x86_64 but I know the issue has been reported as occurring in SLES too. I've been provided Kernel packages that don't have the problem, if you raise a Service Request I expect SUSE will send you fixed packages for SLES. There will inevitably be a fix released via normal channels but I don't know when.

how do I raise a service request with a basic support subscription?

sorry that was a bit short.

We have a basic subscription and that means we cannot raise a service request. The interface just doesn't let you.
The real problem is not that I am in need of "service" (because i already worked around the problem). The real problem is, that there is no way to file a "bug report".

There was once a possibility in the NCC to file bug reports (not service requests) to make SUSE aware of problems. Though I never got an answer (or request for more info) through that channel, I could at least fire a bug and hopefully make somebody aware of a flaw. That is gone now - no bug reports.

That's why I'm reporting to the forum - it's the only channel available.

Maybe I missed something - I'm always eager to learn :)

There's a bug report form at https://www.suse.com/support/report-a-bug/
But as I said, I'm pretty sure the issue you're seeing is something SUSE are already aware of.

thank you - I wasn't aware of the new home for the form.

Kernel update has been released. version 3.0.101-0.47.52.1. Information page says


The SUSE Linux Enterprise 11 SP3 kernel was updated to fix a severe regression.

Due to a broken source patch, accessing NFSv4 servers as a client caused Oops messages and program hangs. (bsc#864409,bsc#924282)
