Or at least warn? It would be possible to detect, the firmware version can be read with: $ sudo lspci -d 1106:3483 -xxx | awk '/^50:/ { print "VL805 FW version: " $5 $4 $3 $2 }' VL805 FW version: 00013500 imho it would be a good idea for Linux to track the latest firmware versions for *all* hardware and warn if a firmware is out-of-date (even if the firmware updater is only available on Windows). Earlier this year I had an intermittent issue with a new laptop where the desktop would hang and processes would get IO errors. But this only happened once every 3 weeks or so. It took a few months to isolate the problem to NVME firmware (it was a HP laptop with Intel NVME, and I was unaware that these drives have locked HP-specific firmware). The firmware update was a Windows executable. I've also seen many forum posts where people have problems that were resolved by updates to GPU/motherboard/NVME/ethernet/wifi etc. firmware. Many of these problems could have been resolved a lot quicker if the kernel log contained "old firmware detected!". -- You may reply to this email to add a comment.
