Hi, Dima How to verify this bug ,Is runing HCK "Plug and Play job" enough ? BTW, We have MSFT Manual Errata about Plug and Play job hangs at "TestSurpriseRemove operation timed out" details referring to Bug 834230 ,Will your patch make QE no more hit this issue ? Thanks, Mike
Hello Mike, Sorry for not answering before, I've missed your comment. This is a theoretic case, I'm not sure it is possible to reproduce it artificially. In any case, please run "Plug and Play job" and verify there is no regression. Also I'm pretty sure this is not the reason why we observe "TestSurpriseRemove operation timed out" in this test, so errata still needed. Dmitry.

In a word,we can use manual errata #1019 to filter the failure for win2k3-32/64 via build 64. FYI, Manual Errata #1019 - Job:Plug and Play job description:Plug and Play job hangs at "TestSurpriseRemove operation timed out".It is ever requested by Yan. Any issues please let me know.
