[SOLVED] Log Spam from RTS5139 staging module

business_kid · 08-06-2014, 07:17 AM

This module works, but fills dmesg with crap - log spam. All this continually while it's doing nothing. Some overzealous debug mode? Kernel 3.14.5

Code:

It gets difficult to make sense of dmesg, when this this crap keeps filling it. Any way to stop it?

Found this.

Apparently, it automatically selects 'rts5139 debugging'. I cannot imagine myself selecting it but it was checked. The module works, but is sad. The TODO states

Quote:

TODO:
- support more USB card reader of Realtek family
- use kernel coding style
- checkpatch.pl fixes
- stop having thousands of lines of code duplicated with staging/rts_pstor
- This driver contains an entire SD/MMC stack -- it should use the stack in
drivers/mmc instead, as a host driver e.g. drivers/mmc/host/realtek-usb.c;
see drivers/mmc/host/ushc.c as an example.
- This driver presents cards as SCSI devices, but they should be MMC devices.
TODO lines 1-9/9 (END)

One more kernel rebuild coming up . . .
