One possible workaround is to make the device use identity mapping, but that requires change the kernel source code. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1931106 Title: bnxt_en NIC driver crashes IO_PAGE_FAULT Status in linux package in Ubuntu: Incomplete Bug description: Hi all, We received a bunch of new servers with a Supermicro H12SSL-NT mainboard that has an embedded Broadcom BCM57416 NIC.

[Kernel-packages] [Bug 1931106] Re: bnxt_en NIC driver crashes IO_PAGE_FAULT
Update: I've contacted the mail addresses from the Kai-Heng's post. Michael Chan (from Broadcom) replied that they've seen similar issues on other AMD systems and that they were working with AMD to resolve this. The plan was to establish contact between me and AMD, unfortunately this never happened. The attempt to contact AMD via the official way (tech support) failed because I could not answer AMD's questions without feedback from Broadcom, who then also did not reply anymore. Workaround: Luckily, with the information that came out of the conversation with Broadcom, I was able to troubleshoot a bit myself since I knew at least somewhat where to look. It appears that by setting Advanced -> NB Configuration -> IOMMU to "disabled" (default is "Auto") in Supermicro BIOS the problem does not occur anymore. Since then the whole topic is "stuck". It's just a workaround and not really a fix, but at least servers running stable now for me. Since I don't know where the actual problem is (whether in AMD hardware, bios, kernel, or whatever) so I can't say if this bug report can be marked as closed or not. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1931106 Title: bnxt_en NIC driver crashes IO_PAGE_FAULT Status in linux package in Ubuntu: Incomplete Bug description: Hi all, We received a bunch of new servers with a Supermicro H12SSL-NT mainboard that has an embedded Broadcom BCM57416 NIC.

Did that, and after ~1 hour after I put them back in production 4 out of 5 servers I've upgraded to v5.13-rc5 crashed and the last after one more hour.
