In case its not, does that kernel include commit 86577c661?
No, it does not but unfortunately this fix does not solve the crash.
However, before you spend too much time on this I'll check 2.6.25.6 and
2.6.26-rc to make sure this problem has not been solved already.
Thanks, please let me know how it turns out.
Clean 2.6.26-rc5 kernel, no additional patches at all.
