Description (last modified by waddlesplash)

I've been experiencing some occasional crashes / KDLs while using QupZilla with my Intel Pro Wifi 4965. This is happening on a physical machine, a Lenovo T430 laptop. The crash is semi-random, but usually seems to be when QupZilla is connecting to a web site or I'm refreshing a page. Other internet apps like Vision don't run into this, so I think there's some sort of interaction between the Qt5 library and the network driver causing this.

Here's the relevant syslog snippet and I'll attach the full file to the ticket. Please let me know if there's other data I can provide

PANIC: vnode 3:2097166 already exists (node = 0xd2faa800, vnode->node = 0xd2fad518)!

Summary: QupZilla crash using Intel pro wifi 4965KDL: PANIC: vnode 3:2097166 already exists (node = 0xd2faa800, vnode->node = 0xd2fad518)!

The WiFi driver panic is separate but probably related; my guess is that the KDL occurs at some unforunate time when the driver is expected to handle interrupts within a few ms, and since the KDL occurs it has to wait multiple seconds, which it doesn't like.

Hmm, on further inspection, this one looks different than that: the message is the same, but this one is on file creation, not directory creation. But I'll CC axeld so he can make the final call.

It seems the backtrace in here is nearly identical to #5753, which was one of the ones supposedly fixed with hrev51061. So, not sure what's going on here.

I ran checkfs at waddlesplash's advice: Since then my system has been stable. Most of the repaired portions of the fs appear to be related to web browsing cache files

here is the checkfs output:

Closing as fixed, then.
