The commit "Restrict usage of GPIO chip irq members before
initialization" breaks suspend on a Dell Inspiron 5515 laptop in a
very severe way. Suspending with this commit present causes the
machine to lock up hard. The only way to recover is to disconnect
mains power, open up the case, disconnect the battery, and hold down
the power button. Bisecting pointed to
2c1fa3614795e2b24da1ba95de0b27b8f6ea4537 in 5.16.20. Testing with the
source commit, 5467801f1fcbdc46bc7298a84dbf3ca1ff2a7320 confirmed that
it was the one that introduced the problem. Unfortunately, this commit
was backported to multiple stable kernels: 5.17.3, 5.16.20, 5.15.34,
and 5.10.111.
I have not yet done any debugging to determine exactly why this commit
causing things to break, but am happy to try out any fixes over the
next couple of days until I put my laptop back together properly.
Hi Daniel,
FYI, The fix for the bug has already been sent by Mario and it has been
picked up by Linus.
