@slawblauciak is this caused due to incorrect amixer settings? |
|
@ranj063 they're not. I've created this issue in line what you said - the fact that the kernel is not currently working properly with the master branch of SOF FW. |
|
Need to monitor if PR #182 can help on this issue. |
|
Set to P1 since we need to assist firmware engineers to set up ChromeOS on Yorp |
|
@slawblauciak as #186 is merged, can you retry? |
|
That PR will likely fix a different issue we were having with suspend. |

We had many syzbot reports that seem to be caused by use-after-free of struct fib6_info. ip6_dst_destroy(), fib6_drop_pcpu_from() and rt6_remove_exception() are writers vs rt->from, and use non consistent synchronization among themselves. Switching to xchg() will solve the issues with no possible lockdep issues.

Attempting to enable HDMI/DP on Yorp [GLK] results in an IPC error:
