https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222624 Hans Petter Selasky <hselasky@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mjg@FreeBSD.org --- Comment #13 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Do you have a core dump of the last crash? Can you run gdb: gdb file /boot/kernel/ehci.ko info line *(void *)(ehci_check_transfer+0x94) In my system this leads to the xfer->td_transfer_cache is NULL. This variable should not be NULL during regular usage. This might be an indication of another memory problem or maybe a mutex issue. It would be interesting to dump some structures to see if their contents is valid. --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
