I'm planning on submitting a bug, but thought I'd poll the population |
2 |
first since I'm having trouble putting together a good bug report |
3 |
(solid lockup). |

It's been a while since I updated the kernel on my T61, was at |
6 |
hardened-sources-3.2.1. Updating to 3.3.6 this week produced a viable |
7 |
kernel, but when X starts the system locks hard. In trying different |
8 |
kernels I've found that the regression is somewhere between the |
9 |
3.2.2-r1 and 3.2.11 versions in the mainstream portage tree. The |
10 |
following is the only dump I've been able to capture, as about 9/10 |
11 |
the system locks beyond SSH recovery; apologies for the zram/zcache |
12 |
taint, it was captured before I started debugging and eliminated |
13 |
those. It is, however, consistent with all subsequent ones I've seen |
14 |
(same IP, same call trace). I do notice that 'make oldconfig' in the |
15 |
3.2.11 tree with the config from 3.2.2-r1 comes up with a single new |
16 |
option, CONFIG_KCOPY. Thoughts? |
