The manpage for modprobe mentions that dashes and underscores are
treated interchangeably in module names.  The stack trace dumps seem to
print module names with underscores.  Use bash to replace _ with the
pattern [-_] so that file names with dashes or underscores can be found.

For example, this line:
[   27.919759]  hda_widget_sysfs_init+0x2b8/0x3a5 [snd_hda_core]

should find a module named snd-hda-core.ko.
