Package: linux-modules-2.6.26-2-xen-amd64 Version: 2.6.26-24 Severity: critical Justification: breaks the whole system
We're using a two node cluster with drbd and ocfs2 as filesystem, exported via NFS to some webnodes. The nfs clients use the nordirplus mount option. We had the reboot one of the cluster nodes due to the following kernel BUG. Looks like debian bug #506950 to me. Upstream has a fix: http://www.mail-archive.com/ocfs2-us...@oss.oracle.com/msg03855.html Here's the BUG: [140488.568363] (5423,0):ocfs2_inode_lock_update:1977 ERROR: bug expression: inode->i_generation != le32_to_cpu(fe->i_generation) [140488.568422] (5423,0):ocfs2_inode_lock_update:1977 ERROR: Invalid dinode 130037 disk generation: 3505630863 inode->i_generation: 3505492205 [140488.568500] ------------[ cut here ]------------ [140488.568527] kernel BUG at fs/ocfs2/dlmglue.c:1977!
