FYI : |
21 |
Just tried a different compile. |
22 |
Switched off expert and flipped the CPU to "Generic x86_64" ( no other |
23 |
changes ). |
24 |
|
25 |
It compiled. ?????? |
26 |
|
27 |
So ... what you choose for CPU in the kernel determines if the |
28 |
ext2/ext3/ext4 fs driver will compile. |
29 |
|
30 |
Been using Gentoo / "sys-kernel/gentoo-sources" w/experimental for 3+ |
31 |
years now. |
32 |
First time the CPU choice has caused a problem. |
33 |
|
34 |
Suspect that a mismatch of the "Spectre / Meltdown" patches that have |
35 |
somehow gotten into the ext4 fs driver and the code for specific CPUs. |
36 |
|
37 |
Wonderful ... just finished a complete reload of Gentoo. Now have to |
38 |
redo it again ... |
39 |
... the mistake? I used ext2/ext3 for the fs. |
