mav 2011-04-14 07:49:45 UTC FreeBSD src repository Modified files: sys/dev/mvs mvs.c mvs.h Log: SVN rev 220615 on 2011-04-14 07:49:45Z by mav Refactor hard-reset implementation in mvs(4). Instead of spinning in a tight loop for up to 15 seconds, polling for device readiness while it spins up, return reset completion just after PHY reports "connect well" or 100ms connection timeout. If device was found, use callout for checking device readiness with 100ms period up to full 31 second timeout. This fixes system freeze for 5-10 seconds on drives hot plug-in.
