Petersen" --=-P4/Zy+tmffVGVYvhXMOq Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi, since kernel 4.11 (sorry it took so long to report) I have a box failing to boot with a NULL pointer dereference (the box is stuck there afterwards). The bug has also been reported to the Debian BTS (https://bugs.debian.org/c= gi- bin/bugreport.cgi?bug=3D882414) and a suggestion to revert 90965761 has bee= n made. I can confirm it fix the boot issue. I don't have the complete stack trace at hand but there's an example in the Debian bug. The machine is a Dell Precision T5600 with the following SATA controllers: 00:1f.2 SATA controller: Intel Corporation C600/X79 series chipset 6-Port S= ATA AHCI Controller (rev 05) 05:00.0 Serial Attached SCSI controller: Intel Corporation C602 chipset 4-P= ort=20 SATA Storage Control Unit (rev 05) If you need more information or need me to test something, please ask.
