SV: sky2 driver



Thanks...

I have applied the patch now, and I'll tell you if it works for me.
Will this patch be added to next kernel-release?

You need this patch, there is a race in the status handling.

Fix a hang on Yukon-EC (0xb6) rev 1 where suddenly no more interrupts were
delivered.

I don't know the real cause of the hang due to lack of docs, but the patch
has been running stable for a few hours whereas the unmodified driver will
hang after less than 2 minutes.
