Add verbose error output for when unexpected i/o errors happen. This eases the burden of debugging and reporting i/o errors. No error information is printed in the success case, here is an example of what is output on error: cio device error ssid : 0x0000000000000000 cssid : 0x0000000000000000 sch_no: 0x0000000000000000 Interrupt Response Block Data: Function Ctrl : [Start] Activity Ctrl : [Start-Pending] Status Ctrl : [Alert] [Primary] [Secondary] [Status-Pending] Device Status : [Unit-Check] Channel Status : cpa=: 0x000000007f8d6038 prev_ccw=: 0x0000000000000000 this_ccw=: 0x0000000000000000 Eckd Dasd Sense Data (fmt 32-bytes): Sense Condition Flags : Residual Count =: 0x0000000000000000 Phys Drive ID =: 0x000000000000009e low cyl address =: 0x0000000000000000 head addr & hi cyl =: 0x0000000000000000 format/message =: 0x0000000000000008 fmt-dependent[0-7] =: 0x0000000000000004 fmt-dependent[8-15]=: 0xe561282305082fff prog action code =: 0x0000000000000016 Configuration info =: 0x00000000000040e0 mcode / hi-cyl =: 0x0000000000000000 cyl & head addr [0]=: 0x0000000000000000 cyl & head addr [1]=: 0x0000000000000000 cyl & head addr [2]=: 0x0000000000000000 The Sense Data section is currently only printed for ECKD DASD.
