During kexec, we perform the device_shutdown() which should bring the device to a known sane state and a reset is not required while next kernel is coming up. I think this fix just masks Yinghai's problem and as such does not fix the root cause of the problem. In his case a software reset of the card is not successful and this is a problem. This problem will become visible during kdump. So I would think that this regression is still there just that got shifted from kexec to kdump. But we do need above patch to make sure kexec boot is fast and does not perform any unrequired device reset. Thanks Vivek ^ permalink raw reply [flat|nested] 7+ messages in thread

The card in question that the regression is reported against is not a released card and as such could have a flawed environment, Hardware, Firmware or other Incompatibility. The fix for the root cause will likely not touch the driver or the kernel. It does raise the specter of a possible follow-on patch to address the root cause under kdump should we determine that the problem can not be solved in time of release of the Firmware of the current pre-released card or if we discover that other released cards have a similar Firmware or Hardware bug. Speculation such as these do not belong on kernel regression reports IMHO.
