G'day
Happens at attempt to defragment InnoDB datafile by xfs_fsr.
lights innodb # xfs_fsr ib_logfile1 (of ~5G size) (all & only innodb-related files lie on the xfs partition)
Hardware Environment: Dual Opteron 246 / Iwill DK8S2 [AMD-8111] / 4G RAM/ LSI 320-2X
Software Environment:[ 2.6.10-rc2-bk13/16 reiserfs(mount as root),xfs ], gcc (GCC) 3.4.3 (Gentoo Linux 3.4.3, ssp-3.4.3-0, pie-8.7.6.6), glibc-2.3.4, xfs_fsr, mysql(with InnoDB)
Btw, I couldn't find any xfs staff in trace, and it seems reiserfs related more here. Oops 100% repeatable for us with 2.6.10-rc2-bk13 and 2.6.10-rc2-bk16
I send it to bugzilla.kernel.org: http://bugme.osdl.org/show_bug.cgi?id=3854
Here is a trace (ksymoopsed)
