I noticed that the broken kernel is apparently some self-built kernel, possibly with extra patches. Still, I'd like to make sure it works fine if at all possible.
It's F12 official, rebuilt with a patch to a network driver. No changes to config.
Could you add the following kernel parameters to the command line of the broken kernel? noexec=off nopat acpi_enforce_resources=lax highmem=0K iomem=relaxed
The character after "highmen=" is a zero.
OK :)
A combination of these parameters may fix it.
No change with all of the above included :(
Hmm doing an strace shows:
sys_physmap_rw_uncached (phys_addr=FFF00000, size=1048576) { mmap2(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_SHARED, 5, 0xffffffffffffff00) = -1 EOVERFLOW }
I at first thought that strace was just getting it wrong, but perhaps something (glibc?) is messing up and doing a signed right shift of the address, and thus mangling the address.
more digging...
cheers, Pádraig.
