I submitted this possible bug months ago to maintainer. No response for whatever reason and the potential bug persists [or I am in error ;-) ]. -- Ron H.

1. Sound driver opl3sa2.c: Possible incorrect display of port number
2. Output from /var/log/messages; Jun 14(unpatched), Jun 18 (patched)
The suspect output is in line 2 "Search for a card at"

Jun 14 11:15:45 micron kernel: opl3sa2: Found OPL3-SA3 (YMF715 or YMF719)
Jun 14 11:15:45 micron kernel: opl3sa2: Search for a card at 0x880.
Jun 14 11:15:45 micron kernel: opl3sa2: Control I/O port 0x370 is not a YMF7xx chipset!

Jun 18 21:43:53 micron kernel: opl3sa2: Found OPL3-SA3 (YMF715 or YMF719)
Jun 18 21:43:53 micron kernel: opl3sa2: Search for a card at 0x370.
Jun 18 21:43:53 micron kernel: opl3sa2: Control I/O port 0x370 is not a YMF7xx chipset!

Note that 0x370 = 3*256 + 7 * 16 = 880 ; port 0x370 incorrectly displayed as 0x880

An attempt at a patch (patch program run from /usr/src/linux):
