On the corrupted firmware bit, the problem ultimately was a combination |
13 |
of the dunder-headed hardware/firmware implementation (blindly accepting |
14 |
any random write as new firmware without even verifying a checksum!), now |
15 |
corrected in newer firmware I believe, and a bug in ftrace. If you never |
16 |
had the ftrace kernel option turned on in kernels you ran on that |
17 |
hardware, as is presumably the case with production server hardware, or |
18 |
if you had it turned on but only in kernels AFTER the fix, the single |
19 |
known triggering bug vector will have never been available, so it's very |
20 |
unlikely you have it. |

Other than that, I don't have any direct experience with that hardware, |
26 |
so I'm not going to be of much help, I'm afraid. |
