Same system works without issue on built in wm0 ure0: discarding oversize frame (len=1757) ure0: discarding oversize frame (len=8136) panic: pool_redzone_check: [mclpl] 0x3c != 0xb0 cpu0: Begin traceback... vpanic() at netbsd:vpanic+0x152 snprintf() at netbsd:snprintf pool_sysctl() at netbsd:pool_sysctl pool_cache_put_paddr() at netbsd:pool_cache_put_paddr+0x33 m_ext_free() at netbsd:m_ext_free+0xed m_free() at netbsd:m_free+0x76 m_freem.part.7() at netbsd:m_freem.part.7+0xe ether_input() at netbsd:ether_input+0x3cb if_percpuq_softint() at netbsd:if_percpuq_softint+0x90 softint_dispatch() at netbsd:softint_dispatch+0x108 DDB lost frame for netbsd:Xsoftintr+0x4f, trying 0xffffa80255c840f0 Xsoftintr() at netbsd:Xsoftintr+0x4f --- interrupt --- 56e7da84c242f3ce: cpu0: End traceback... xhci0 at pci0 dev 20 function 0: Intel 100 Series xHCI (rev. 0x21) xhci0: interrupting at msi0 vec 0 xhci0: xHCI version 1.0 usb0 at xhci0: USB revision 3.0 uhub0 at usb0: NetBSD (0x0000) xHCI root hub (0x0000), class 9/0, rev 3.00/1.00, addr 0 uhub0: 6 ports with 6 removable, self powered uhub3 at uhub0 port 4: VIA Labs, Inc.
