Hello All, Can anyone point me towards someone to help diagnose an issue I have with a pure64 box panicing when it comes under load? I am running 2.6.8-rc1 with pure64/unstable (as of two days ago or so, but its been the same for the last few weeks so I don't think userspace is the issue). I have LVM2 partitions with XFS on top of it. I have MySQL sitting on top again, and each time I do a mysqldump I get the following, repeatable, panic: ----- BEGIN SCREEN SCRAPE ---- CS: 0010 DS:: 0018 ES: 0018 CR0: 000000008005003b CR2: 000000000005fe008 CR3: 00000000000101000 CR4: 00000000000000006e0 Process pdflush *pid: 44, threadinfo 0000010008132000, task 0000010008131170) Stack: 0000010008133cb8 00000101fc1072f0 0000010008133e48 ffffffff8015dc0a 0000000000000001 ffffffff801969ff 0000000000000000 ffffffffa0101980 0000000000000000 00000101ffe3a308 Call Trace: <ffffffff8015dc0a>{pagevec_lookup_tag+26} <ffffffff801969ff>{mpage_writepages+623} <ffffffffa0101980{:xfs:linvfs_writepage+0} <ffffffffa00e52b8>{:xfs:xfsflush+744} <ffffffff8019501f>{__sync_single_inode+111} <ffffffff8019546f>{sync_sb_inodes+495} <ffffffff801955d4>{writeback_inodes+132} <fffffffff801586fc>{wb_kupdate+2} <ffffffff801592a0>{pdflush+0} <ffffffff801591e9>{__pdflush+297} <ffffffff801592bc>{pdflush+28} <ffffffff80158650>{wb_kupdate+0} <ffffffff8014a002>{kthread+146} <ffffffff80111447>{child_rip+8} <ffffffff801592a0>{pdflush+0} <ffffffff8014a040>{keventd_create_kthread} <ffffffff80149f70>{kthread+0} <ffffffff8011143f>{child_rip+0} Code: 7e f8 e9 f5 da ff ff e8 ba 55 15 00 e9 c4 fb ff ff e8 5e 56 consoel shuts up ... ----- END SCREEN SCRAPE ---- Can anyone here grok this, and tell me if I should be talking to maintainers for LVM, XFS, or someone completely different? Has anyone else had issues with pure64 and 2.6 kernels when doing large I/O? If anyone is interested, I can send kernel config and any other relevant data.
