So yes, a bisection would be great. Tejun, all the problematic patches are yours - so adding you. Neil, since the problem only occurs whilst an xfs filesystem is mounted on a raid6 array, I've cc'ed you too... OK Got as far as I could... I've run 9 or 10 kernels/bisects and got to a point with 8 of Tejun's changesets where it wouldn't compile: CC drivers/ata/sata_via.o drivers/ata/sata_via.c:120: error: `ata_scsi_device_suspend' undeclared here (not in a function) drivers/ata/sata_via.c:120: error: initializer element is not constant drivers/ata/sata_via.c:120: error: (near initialization for `svia_sht.suspend') drivers/ata/sata_via.c:121: error: `ata_scsi_device_resume' undeclared here (not in a function) drivers/ata/sata_via.c:121: error: initializer element is not constant drivers/ata/sata_via.c:121: error: (near initialization for `svia_sht.resume') make[2]: *** [drivers/ata/sata_via.o] Error 1 git bisect visualise gave: bad: 48aaae7a2fa46e1ed0d0b7677fde79ccfcb8c963 bisect: 54936f8b099325992f0f212a5e366fd5257c6c9c good: 0a3fd051c7036ef71b58863f8e5da7c3dabd9d3f I used: git reset --hard 8575b814097af648dad284bd3087875a11b13d18 git reset --hard e92351bb53c0849fabfa80be53cbf3b0aa166e54 git reset --hard 3a32a8e96694a243ec7e7feb6d76dfc4b1fe90c1 git reset --hard 9666f4009c22f6520ac3fb8a19c9e32ab973e828 to step through - non compiled git reset --hard 1d30c33d8d07868199560b24f10ed6280e78a89c compiled and hung on resume. given the first patch identified is 9666f4009c22f6520ac3fb8a19c9e32ab973e828: "libata: reimplement suspend/resume support using sdev->manage_start_stop" That seems a good candidate... Incidentally, when I compile 1d30c33d8d07868199560b24f10ed6280e78a89c (far side of the implicated changesets) if I umount my xfs over raid6 filesystem (no lvm as I said in the OP) the resume succeeds.
