Forwarding bug report from bugzilla #153211 as requested: System crashes completely during or immediately after installing APK to android phone over usb using android studio. I was unable to reproduce this bug any other way. The only way to recover after the crash is a hard restart, netconsole captures the following at the time: [10592.718753] NMI watchdog: BUG: soft lockup - CPU#2 stuck for 23s!

[java:18908] Bisecting shown that commit 86065c2719 "xhci: don't rely on precalculated value of needed trbs in the enqueue loop" somehow introduced the issue, but I can't find how. Please let me know how I can help to fix this.
