I have the same exact message since June 11 boot (probably the day after updating to 427). In addition I'm now running the 435 kernel and the message persists. The message comes from drivers/base/bus.c and the only patch that seems to touch that file between 2.6.5-1.358 and 2.6.6-1.427 is from an update to the mainline kernel: akpm at osdl dot org [PATCH] fbdev: Vesa Fbdev update Of course, the cause could run much deeper, but -- not being a kernel hacker -- I quickly got lost in a maze of twisty little kernel module functions. Same error message with kernel-2.6.7-1.494.2.2. Its still present in kernel-2.6.8-1.521 Created attachment 103082 [details]
bus.c diff ignoring not only -ENODEV but also -ENXIO in probe callbacks
It has to be confirmed that -ENXIO is as ignorable as -ENODEV...
Disclaimer: I don't have enough knowledge to this, so take my patch
with a grain of salt.
Explanation: the bus.c file invokes a probe callback for most devices
in a list, then checks for -ENODEV return ("no such device"), if so it
remains silent. However, some drivers (including vesafb.c) may return
-ENXIO ("no such device or address"), which is indeed error -6.
I shut up the warning with the attached patch, that basically ignores
both -ENODEV and -ENXIO.
Looks like the problem is still in kernel 2.6.9. I am still getting this message: vesafb: probe of vesafb0 failed with error -6...: 3 Time(s) in my boot log. This problem is still here in FC3 using kernel-2.6.9-1.681_FC3 Should I change the version field of the bug to reflect this? It seems to me that the posted patch needs to be applied to the linux kernel source code, which implies that one has to recompile the kernel. If so, how come that future versions of the core are not patched? I'm currently on 2.6.9-1.681_FC3 and the error persists Fix noted in the changelog for FC3 update kernel-2.6.9-1.724_FC3. Fix confirmed working for me. |
