Kevin, thanks for your patch. I've tested yesterday for several days. And it works very well solving all the reset racing problems i've met. > >-Kevin > > >Kevin O'Connor (2): > resume: Make KVM soft reboot loop detection more flexible > post: Always set HaveRunPost prior to setting any other global > variable > > src/fw/csm.c | 1 + > src/fw/shadow.c | 17 +++++++++++++++-- > src/fw/xen.c | 1 + > src/post.c | 20 ++++++++++++++++---- > src/resume.c | 9 --------- > src/util.h | 1 + > 6 files changed, 34 insertions(+), 15 deletions(-) > >-- >2.5.0 > _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
