Hi, I'm busy updating to the latest factory kernel and have received the following errors from kernel-default-base installation (I did insert a blank dvd during the installation of the rpm by zypper):- WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sd_mod.ko needs unknown symbol crc_t10dif WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol register_cdrom WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_ioctl WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_media_changed WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_get_media_event WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_release WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_open WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol unregister_cdrom WARNING: /lib/modules/2.6.29-rc8-5-default/kernel/drivers/scsi/sr_mod.ko needs unknown symbol cdrom_number_of_slots And then these errors which I think IIRC happened before when the kernel was first split into three:- Kernel image: /boot/vmlinuz-2.6.29-rc8-5-default Initrd image: /boot/initrd-2.6.29-rc8-5-default Root device: /dev/disk/by-id/ata-WDC_WD800JB-00JJC0_WD-WMAM9RA78067-part3 (/dev/sda3) (mounted on / as xfs) Resume device: /dev/disk/by-id/ata-WDC_WD800JB-00JJC0_WD-WMAM9RA78067-part2 (/dev/sda2) FATAL: Module processor not found.

VirtualBox fails under kernel 5.18
by Larry Finger 23 May '22

23 May '22

VirtualBox fails to run correctly under kernel 5.18.0. I noticed a problem in the 5.18-rcX cycle and bisected the problem to commit 6e8ec2552c7d ("random: use computational hash for entropy extraction"). That commit has been confirmed as the one causing the problem. We now know the cause. The changes in the random number generator employ the SSSE3 instructions. which in turn affects the FPU. The current belief is that the VirtualBox vcpu is not saving the state of the FPU when a hard IRQ occurs. If any code using SSSE3 runs in the host during that interrupt, the state of the FPU in the guest is incorrect, and the guest gets a kernel exception. Thus far, the only kernel code using that instruction set is the random number generator. It is easy to test for this condition. In the guest start a multi-cpu build of the kernel, or some other large project. Within a few seconds, gcc will get an error. The attached patch will cause rng not to use SSSE3 instructions, thereby bypassing the problem. Generation of random numbers may be a bit slower, but have no loss of robustness. If possible, I would like the patch applied to 5.18.X kernels until Oracle fixes the problem. Finding the fault is beyond my understanding of the implementation of virtual CPUs.

[kernel] TW amdgpu firmware regression?
by Felix Miata 19 May '22

19 May '22

As of kernel-firmware-amdgpu-20220411 (first bad), and sometime after kernel-firmware-amdgpu-20211123 (last available good to revert to), and after TW20220311 (last working), using TW20220517 on: AMD Oland [Radeon HD 8570 / R5 430 OEM R7 240/340 Radeon 520 OEM] vendor: Dell driver: amdgpu v: kernel active: DP-1,DVI-I-1 bus-ID: 01:00.0 chip-ID: 1002:6611 aka Southern Islands GCN 1st gen microarchitecture Display and keyboard lockup around the time KMS should init. Other than reverting the firmware, or the crippling nomodeset option, the only workaround I have found is installing kernel-firmware-radeon, which this PC/GPU combination has never before needed. With kernel-firmware-radeon installed, X nevertheless runs using the amdgpu kernel module and the amdgpu DDX or the modesetting DIX. Before I report a bug, I would like to know if anyone here on the kernel mailing list knows if perchance GCN1 support has been purposely removed somehow from kernel-firmware-amdgpu, thus negating any point for a bug report. dmesg using 20211123 kernel-firmware-amdgpu: https://susepaste.org/6218560 dmesg using 20220411 kernel-firmware-amdgpu: https://susepaste.org/2000260 -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
