Still broken in 2.6.15. With all the debugging options OFF in the config,

no ping. Note that this is different from before: it actually ran a
little bit before locking up, rather than locking up within seconds like
it did with 2.6.15-rc5.
I couldn't quite tell from your description: are you getting the lockup
when you try to mount a filesystem that uses the RAID+LVM as a device?
Or do you get errors when doing LVM-level stuff (ie no filesystem can
even be put on the device)?
In the case of the former, what filesystem are you using?
No errors ever, just hard lockups.
Just wanted to add that I recently starting to see similar behaviour (hard
lockups with no errors during heavy writing to the filesystem) on
raid5+lvm+reiserfs after adding 6 sata_sil-connected disks in raid5 to an
already existing vg of a couple of pata raid5s. This is 2.6.14 though, and
I haven't ruled out hw issues yet (going to put a beefier PSU in it
first), but it might be related.
I'm going to try adding debugging symbols to make it stable after the PSU
upgrade, if that doesn't fix it. :)
