- The MIPI camera with Intel IPU6/IPU6EP is an experimental feature that is not recommended for enterprise users for the reasons below:
- Intel does not have a plan to upstream the kernel patches for MIPI camera sensors.
- Poor quality of camera performance: 720p 30fps
- CPU performance is impacted by a daemon doing buffer copying for v4l2 loopback device.
LP:#1889384 ASPM not enabled on child devices behind VMD controller
- symptom: Intel TGL cpu can not get into package C10 sleep state in VMD mode.
- impact: Power consumption is high during long idle and suspend to idle
- workaround: set AHCI mode in BIOS instead.
LP:#1890772 No signal on 4K 60Hz DisplayPort monitor by default, until "max bpc" is lowered to 8
- symptom: compatibility issue across the connector, dongle, cable to monitor. User can workaround it by lower "max bpc" by a command to reduce the bandwidth requirement on 4K@60Hz.
LP: #1889539 System power cutoff unexpectedly when running unigine-heaven benchmark
- symptom: System shutdown when Nvidia graphic is processing heavy loading. Nvidia driver not yet provide a cooling way when thermal on Nvidia graphic over temperature.
LP: #1839309 "calling nvidia-smi in udev rule is a gap to the driver from Nvidia"
- symptom: System fails to boot in performance mode.
- impacted platforms: Precision 7730, Precision 7530, Precision 7540, Precision 7740 that with NVIDIA N18E series chips [10de:1bb5], [10de:1bb9] and [10de:1bbb].
LP: #1857865 "storage created raid by BIOS can not be recognized in AHCI mode"
- symptom: Raid disks on Windows edition machines can not be recognized on Ubuntu.
LP: #1866156 "Wireless LAN RF is hardware blocked forever after r8153 ethernet connected."
- symptom: If a user enables runtime PM for r8153 ethernet dongle, then wifi radio be hard blocked by BIOS.
goodix fingerprint proprietary driver is supporting limited devices after Focal.
LP: #1931061 "WiFi cannot find AP if scan for a while (Intel AX210)"
LP: #1843588 "Nautilus doesn't copy filenames for paste to other programs anymore"
- symptom: Reverting the problematic commit will fix the usecase reported in this bug (and all applications where copying from Nautilus and pasting the data into a text-based input makes sense), but will break copying to/from Desktop Icons extension.
