I've added tons of printf()'s and breakpoints through all that stack of functions and finally reached as far as bd_edd_io(). Exactly it do fail. I've added printf() with all arguments at the beginning of bd_edd_io() and don't see obvious differences between argument sets that do work and argume= nt sets that crush the function. Please help me further. Another thing that I've observed is though the crashes look everytime simil= ar but occur not always exactly after the N's invocation of bd_edd_io(), saying more precisely not after exact bcache_ops variable value (which is incremen= ted in bcache_strategy()). Two adjacent boots with no code and hardware modifications can give differe= nt (but close) bcache_ops values right before crashes. --=20 You are receiving this mail because: You are the assignee for the bug.=
