SubjectRe: [prepatch] removal of oops->printk deadlocks

Hi,

The whole oops produced by the 2.4.0-test11pre4 with this patch is in the
attachment. Other system info is tehere as well.

Oops is produced when runnning big-tables test from mysql sql-bench.
It's reproducable. The machine is running only mysqld.

regards
pkot

ksymoops 2.3.4 on i686 2.4.0-test11. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test11/ (default)
-m /boot/System.map-2.4.0-test11 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
