debian-6.0.5-amd64 spl-0.6.0-rc8 splat -a BUG: soft lockup - CPU#0 stuck for 61s!

[dpchrist]

zfsonlinux / spl issues:

I did a fresh install of debian-6.0.5-amd64 ("Standard system utilities" only) on an Intel DQ67SWB3 with an Intel i7-2600S CPU and built spl-0.6.0-rc8 per http://zfsonlinux.org/spl-building-deb.html. When I run the regression test (in an SSH window), it hangs at:

kmem:slab_overcommit

After a while, groups of messages similar to the following start appearing on the console (one message for each of the 8 cores):

[  383.123] BUG: soft lockup - CPU#0 stuck for 61s! [splat_kmem_cach:3369]

Is there anything I can do to fix this?

HTH,

David

Yes, there is. Several memory management fixes have gone in the latest master source. Can you try the latest untagged version from Github and see if you can recreate the issue. This will be part of -rc9.

I wiped the system and started over with Debian testing Wheezy amd64
20120423-05:08 (the latest disks have bugs and won't install).
spl-0.6.0-rc8 and zfs-0.6.0-rc8 both built and tested correctly.
