linux-toradex.git/drivers, branch v3.12.8 Linux kernel for Apalis and Colibri modules SCSI: sd: Reduce buffer size for vpd request 2014-01-15T23:31:43+00:00 Bernd Schubert bernd.schubert@itwm.fraunhofer.de 2013-09-23T12:47:32+00:00 040b47c80e0d3bca9db9353fe44ca044c273624a commit af73623f5f10eb3832c87a169b28f7df040a875b upstream. Somehow older areca firmware versions have issues with scsi_get_vpd_page() and a large buffer, the firmware seems to crash and the scsi error-handler will start endless recovery retries.

commit af73623f5f10eb3832c87a169b28f7df040a875b upstream.

Somehow older areca firmware versions have issues with
scsi_get_vpd_page() and a large buffer, the firmware
seems to crash and the scsi error-handler will start endless
recovery retries.
Limiting the buf-size to 64-bytes fixes this issue with older
firmware versions (<1.49 for my controller).

Fixes a regression with areca controllers and older firmware versions
introduced by commit: 66c28f97120e8a621afd5aa7a31c4b85c547d33d
