It doesn't really matter what type adapter it is, the igb driver only requests standard size clusters, so memory is getting trashed somewhere I suspect. > > Jack Well, from my observations about this issue (which could be very wrong because my lack of knowledge about BSD kernel) I don't suspect igb driver directly, but rather an order which kernel is processing stuff related to MSIX and hardware (so I suppose that real cause of the problem could be very hard to catch and repeat)? Here's why: 1. There's no panic when using GENERIC kernel. There's also nothing unusual in my custom kernel (included in thread), neither in make.conf. 2. Before current build, panic was seen with igb driver included in kernel, but no panic when using a module. Even better - no panic when trying to load a module while igb driver is stil included in source. No random memory corruption here - same scenario seen every boot with all variants above. It's HP server with HP ECC memory by the way. 3. With current build kernel panics regardless if igb driver is a module or included in kernel (unless i disable MSIX). But I found override - I removed igb driver from kernel config, and a module from loader.conf. Than booted in single user mode, and manually loaded igb driver. No panic! Appareantly something gets wrong _only_ at boot time. -- Bartosz Stec
