On February 2, I posted a tale of woe here. It explained that I wasn’t able to update my Lenovo X380 Yoga past 21296. Each attempt to upgrade to 21301 failed at around 50% complete after the first reboot. And although error messsages did vary once or twice most of the time it threw an IRQL_NOT_LESS_OR_EQUAL bugcheck error. None of my usual troubleshooting techniques afforded any relief, either. Then I got the word from a contact on the Insider Team: this was a known bug, and a fix should be coming “soon.” That’s why I’m pleased to report that Dev Channel Build 21313 fixes bugcheck error just described. It appears number one in the list of fixes shown in lead-in graphic, in fact.

Proof That Dev Channel Build 21313 Fixes Bugcheck Error

I tackled the upgrade on Friday afternoon, February 12. I could only hope for the best. But soon enough, my hopes were rewarded with a complete and successful installation. I always fret when I have to hang back from the leading edge of releases on any of my PCs. That’s because, as a Windows Insider, I take my commitment to keep up with new releases seriously. So again, I’m happy to be back in the high life again (with apologies to Stevie Winwood).

Proof Positive That Feedback Hub Is Working

When the Insider Team contacted me, they made it clear that (a) I was not alone in reporting this problem, and (b) that ongoing repair efforts were underway with a fix in their sights. My benefactor was very clear about asserting that a fix was coming, but might or might not make its way into the next Dev Channel update.

In fact, the Insider Team skipped its usual Wednesday Dev Channel flight on February 3. Then, it didn’t get a flight out last week until Friday, February 12. This is reportedly in the interests of quality and providing needed fixes. All I can say is that, as far as I’m concerned, those reports are on the money. They fixed what ailed my X380 and I’m glad to say “Thanks, Insider Team! Good work.”
