Looks like rtsx mangle kernel memory and it crashes in other places/kernel threads. Have you try dev.rtsx.0.inversion=1 in /boot/loader.conf with the device enabled on BIOS?

And there can be much, much more PCs/chips which need it, but no one has tested yet. My rtsx driver on ThinkPad P52 works fine without it, but IIRC, paniced with it (I did it just a test purpose when it landed). And one more. If you insert write-protected card and then mount it as writable, it SHOULD certainly crash the system. It's not a rtsx driver issue, but promised to happen. I've encountered the problem on USB card readers, too. > > -- > // Lev Serebryakov > _______________________________________________ > freebsd-current_at_freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe_at_freebsd.org" > -- Tomoaki AOKI <junchoon_at_dec.sakura.ne.jp>Received on Fri May 07 2021 - 14:34:57 UTC
