Hi,

I'm seeing the Oops below when trying to boot 5.1.0-rc4 on an ARM PXA3xx
platform. v5.0 did not show this effect with the same cmdline.

Relevant bits from the config are:

CONFIG_NFS_FS=y
CONFIG_NFS_V2=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_SWAP is not set
CONFIG_ROOT_NFS=y
CONFIG_NFS_FSCACHE=y
# CONFIG_NFSD is not set
CONFIG_NFS_COMMON=y

Anything else I can provide? I could bisect the issue if that helps.


Best regards,
Daniel

Please do bisect if that is at all practical. I'm having trouble
interpreting this Oops.

Here you go:

    SUNRPC: Micro-optimise when the task is known not to be sleeping

    In cases where we know the task is not sleeping, try to optimise
    away the indirect call to task->tk_action() by replacing it with
    a direct call.
    Only change tail calls, to allow gcc to perform tail call
    elimination.

Any idea?

Ah... It looks like we explicitly turn off tail call optimisation in
some ARM configs, so this might be a stack overflow.

Does your config file have THUMB2_AVOID_R_ARM_THM_JUMP11 set?

Nope. I don't even have THUMB2_KERNEL.

In the meantime, I tried to trace that with some printks, but the bug
appears evasive, and the backtrace changes as soon as I modify the
timing. Hmm.

Happy to test patches if you have any idea.


Thanks,
Daniel

Could you please try pulling the 'testing' branch from 
http://git.linux-nfs.org/?p=trondmy/linux-nfs.git;a=shortlog;h=refs/heads/testing

i.e. 'git pull git://git.linux-nfs.org/projects/trondmy/linux-nfs.git
testing'

to see if that suffices to fix the issue you're reporting?

Thanks
  Trond

Yes, that revert in your branch fixes the problem. All fine again!
