The hang is in waiting on something outside WebKit: 2821 ??? (in AppleGVA) load address 0x7fff4e9ed000 + 0x3f205 [0x7fff4ea2c205] 2821 ??? (in AppleIntelICLGraphicsVADriver) load address 0x118167000 + 0x16dd9 [0x11817ddd9] 2821 AVD_CreateAVDAccelerator (in AppleIntelICLLPGraphicsVAME) + 1490 [0x117b7624e] 2821 IOServiceOpen (in IOKit) + 39 [0x7fff22c8b395] 2821 io_service_open_extended (in IOKit) + 137 [0x7fff22c8b438] It's not actionable based on the stack trace alone, and also is very unlikely too be a WebKit bug. Could you please file a report with a sysdiagnose at https://feedbackassistant.apple.com for Apple engineers to look into? |
