I'm getting this repeatedly on several machines... after mounting a smbfs
then sitting idle for a while, just an ls -l on the fs causes the panic.
I built a kernel with debug & built smbfs.ko with debug. This is 4.3-BETA
fresh from yesterday. Many identical (minus SMBFS) machines running great
with this same kernel/world.
I'm not sure where to go next... what follows is what I could get out of
gdb... I do not know why there are ?? in the backtrace... maybe it is the
linux.ko... I do have kern.fallback_elf_brand=3 set.
# objdump --section-headers /modules/smbfs.ko|grep text
3 .rel.text 00003f20 00003bd4 00003bd4 00003bd4 2**2
9 .text 0000eb78 00008c7c 00008c7c 00008c7c 2**2
# kldstat
Id Refs Address Size Name
1 6 0xc0100000 255918 kernel
2 1 0xc0356000 9cc0 agp.ko
3 1 0xc0360000 16e64 ipl.ko
4 1 0xc1015000 3000 daemon_saver.ko
5 1 0xc1018000 12000 linux.ko
6 1 0xc1055000 1c000 smbfs.ko
I just built linux.ko with -g and tried to add-symbol-file it, but it made
no difference... I'll install the new linux.ko in case that makes a
difference, but it will probably be at least an hour before I get another
crash...
