https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211836 Andrey V. Elsukov <ae@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |adrian@freebsd.org, | |rwatson@FreeBSD.org --- Comment #4 from Andrey V. Elsukov <ae@FreeBSD.org> --- I guess it is related to RSS option. Your system has many CPU cores, so RSS uses all of them. But netisr has only 2 initialized threads. netisr_select_cpuid() uses rss_soft_m2cpuid_v4() to determine cpuid. Since the last one doesn't limit cpuid with nws_count, we can get cpuid for which we didn't initialized any data. This works for one netisr thread, because we return *cpuidp = nws_array[0], when nws_count == 1. -- You are receiving this mail because: You are the assignee for the bug.
