CVSROOT: /cvs Module name: src Changes by: dera...@cvs.openbsd.org 2011/04/17 22:16:14
Modified files:
sys/dev/pci : pciide.c
sys/dev/ata : ata_wdc.c wd.c
sys/dev/ic : wdc.c wdcvar.h
Log message:
keep an eye out for wdc registers returning 0xff. if they return 0xff,
this probably means the controller is dead -- as in, a hot plug eject
event. in that case, mark the driver dead and try harder to return -1
in the interrupt handler.
tested by many
ok dlg, miod did not object
