Description of problem: modprobe microcode results in error messages: Nov 28 16:32:14 mail kernel: microcode: CPU0 sig=0x106a5, pf=0x2, revision=0x11 Nov 28 16:32:14 mail kernel: platform microcode: firmware: requesting intel-ucode/06-1a-05 (repeat for each cpu). microcode_ctl -f <file> may or may not be loading the correct file - there is no easy way to see. A few obvious issues: 1) microcode-ctl intel firmware is stored generically in /lib/firmware/microcode.dat. firmware.sh is looking for intel-ucode/06-1a-05 in various places including /lib/firmware. 2) Assuming you've got the correct microcode stored in /lib/intel-ucode/06-1a-05, the script then tries to set the 'loading" indicator at /sys/devices/platform/microcode/firmware/microcode/loading. That doesn't exist. Looking at the kernel driver, it doesn't look like it's even used anymore. When I comment out the "loading" lines and override the FIRMWARE variable with /lib/firmware/microcode.dat and then modprobe microcode, I get log messages that suggest success: Nov 28 16:52:47 mail kernel: microcode: CPU0 sig=0x106a5, pf=0x2, revision=0x11 Nov 28 16:52:47 mail kernel: platform microcode: firmware: requesting intel-ucode/06-1a-05 repeated for each cpu Version-Release number of selected component (if applicable): udev-147-2.fc13.x86_64 Was also true for fc12 versions - dk about 11. How reproducible: totally
1) the kernel requests the file, so it should be present in the file system with that name. Maybe a softlink should be provided by the package which provides micocode.dat. 2) I will fix the script to test for the existence of the "loading" file first.
Created attachment 381748 [details] Proposed firmware.sh Please add a symlink to the firmware file in /lib/firmware and test this firmware.sh script, if it fixes your problems.
Fixed - however now that the firmware is found, the loading is unacceptably slow. There are at least two other bugs open for that, so I'd say let's close this one.
