Dear Kernel maintainers, I have been having on-and-off memory corruption problems after hibernate on my Thinkpad X200 (with intel graphics). The symptoms are similar to those described in this report and the others: sometimes a hang after hibernate (after loading the resume image, either before or after X resumes), sometimes segfaults on any new process. I attach an "oops" that was caught in syslog, but often nothing appears in the logs.
After reading this bug report, I had hoped these problems were resolved, but they sadly do not seem to be (neither for 2.6.32-5-amd64 (Debian 2.6.32-21) currently in testing, nor for 2.6.35-trunk-amd64 (Debian 2.6.35-1~experimental.3) currently in experimental). I realise this may not be the most helpful report; please let me know if different information would be useful. With all best regards, Marten
