which image was used here? Please include that in all bug reports. A core-image-sato-sdk. Appears also on 1.8.M2.RC2 (22c38e2d8a058619e3d05534b5e830b750aa4241) I have not spent much time on it. This needs further debugging. Created attachment 2429 [details]
More errors found in the logs.
I just checked this on the Sugarbay machine I was using to look at the tar related issue and did not see this error with that build, please verify this is no longer an issue This issue appears on 1.9_M1.rc2: f9ea480e6c26fea46c3011c4e9d0e2de3d5c81b4, genericx86-64 on NUC and MinnowMax and on genericx86 on MinnowMax.

Since the v86d package installs either a fbsetup script (for sysvinit) or a modprobe.d/uvesafb.conf for systemd. These need to be modified to check for an existing framebuffer driver is installed. - "It appears also on 1.9_M3.rc1: ea562de57590c966cd5a75fda8defecd397e6436 poky commit, core-image-sato-sdk image for genericx86-64 tested on NUC and MinnowMax and genericx86 on MinnowMax." Will checkout this head and do some debugging with generic-x86 & MinnowMax for a solution. This can also reproduced on jethro. Maybe a short-term solution is just disable uvesafb module on non-emu machines as we discussed. I am doing some debugging today towards to these steps and more clues in logs: rmmod uvesafb modprobe uvesafb root@genericx86-64:~# cat /var/log/messages Nov 24 12:03:25 genericx86-64 user.warn v86d: EBDA too big (38800), truncating.

Clarified by FW team, Minnow Board Max BIOS is pure EFI-based and legacy free firmware. That means it doesn't support video bios and ram at these addresses. I think we can disable uvesa on minnow Max or degrade this bug since I don't see any functional impact from this error message. patch has been submitted to poky mailing list today. patch has been merged into poky master brand: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=6af89812e8a9931ffed63768ed85367519bf7aef close it. This should be backported to jethro branch. Verified with master (m2_rc1) and jethro (2.0.1.rc6) Tried on actual hardware minnowmax.
same error log is comming.
STATUS: FAILED
BUILD: 2.3.4 RC1: ebb42af2829edfca1a23c7a51a431c656ffc2090
IMAGE: core-image-sato-sdk_generic-x86_64
ENVIRONMENT: generic-x86_64 on minnowmax
STEPS TO REPRODUCE:
Parse dmesg log and all log files in /var/log for k
keywords like: "error" , "failed" , "cannot", "can't" etc.
Filter out the known and invalid errors or errors that
appear in certain situations and need to be ignored.
I have attached test_image log.

This is a slightly different error message compared to the original bug. Here, the kernel has uvesafb in it but the userspace does not, its missing v86d. This is expected given the original change to remove it from the genericx86 images. This is therefore not a bug. |
