Hi, I got the following OOPS on 2.6.32-41 (Linux version 2.6.32-5-amd64 (Debian 2.6.32-41) (b...@decadent.org.uk) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Mon Jan 16 16:22:28 UTC 2012). The machine runs Mysql, it's a dedicated database server with pretty high IO load.
The oops is hard to read because it was captured via netconsole, but the crash is a divide by zero error in find_busiest_group, like the original report. So this doesn't seem to be fixed in -41. Would upgrading to -45 help? Regards, Ronald.
