Dear Linux SCSI folks, using Debian Sid/unstable with Linux 4.2.3-1 upgrading from systemd 227-1 to 227-2 [1] and other packages, the system doesn’t start up anymore and the /dev/md1 device doesn’t seem to be found and I am dropped into shell from initramfs (BusyBox). Only having wireless LAN and no serial or USB debug capabilities, and mount a USB storage device did not work, I manually copied the beginning of the Oops. ``` BUG: unable to handle kernel NULL pointer dereference at 00000014 IP: [<f828a00c>] sr_runtime_suspend+0xc/0x20 [sr_mod] *pdpt = 000000003696e001 *pde = 000000000000000000 Oops: 0000 [#1] SMB Modules linked in: sd_mod(+) sr_mod(+) cdrom ata_generic ohci_pci ahci libahci pata_amd firwire_ohci firewire_core crc_iti_t forcedeth libata scsi_mod ohci_hcd ehci_pci ehci_hcd usbcore usb_common fan thermal thermal_sys floppy(+) CPU: 1 PID: 73 Comm: systemd-udevd Not tainted 4.2.0-1-686-pae #1 Debian 4.2.3-1 Hardware name: Packard Bell imedia S3210/WMCP78M, BIOs P01-B2 11/06/2009 task: f68dd040 ti: f6988000 task.ti: f6988000 EIP: 0060:[<fh28a00c>] EFLAGS: 00010246 CPU: 1 EIP is at sr_runtime_suspend+0xc/0x20 [sr_mod] EAX: 00000000 EBX: f6a30cd8 ECX: f6c03d2c EDX: 00000000 ESI: 00000000 EDI: f828e100 EBP: f6989ba8 ESP: f6989b88 DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 CR0: 8005003b CR2: 00000014 CR3: 3696d780 CR4: 000006f0 Stack: af83346c3 00000000 00000001 fffffff5 f6a7d150 f6a30cd8 f6a30d3c 00000000 f6989bbc c1390cb7 f6a30cd8 f8334660 00000000 f6989bd0 c1390d0f f6a30cd8 f8334660 00000000 f6989c0c c13916cb f694a614 f68dd040 00000000 00000008 Call Trace: […] ? scsi_runtime_suspend+0x63/0xa0 [scsi_mod] […] ? __rpm_callback+0x27/0x60 […] ``` I tried also to boot with Linux 4.1 and it fails the same way. Is that a known problem and has been fixed in the mean time? It’d be great if you helped me getting the system to boot again. Please tell me if you need more information to debug this issue and I’ll do my best to get it.
