https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217882 Bug ID: 217882 Summary: panic on UEFI boot after recent changes Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: subbsd@gmail.com After recent changes and fixes ( https://lists.freebsd.org/pipermail/freebsd-current/2017-March/065093.html ) I still had problems on host with increased EFI_STAGING_SIZE value. I have custom FreeBSD distribution which has a sufficiently large mfsroot which is loaded through UEFI mode. To solve the problem, it was suggested to increase this variable and rebuild /sys/boot: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209944 Also, it has to be increased periodically for some reason: https://svnweb.freebsd.org/base/stable/11/sys/boot/efi/loader/copy.c?r1=305779&r2=305778&pathrev=305779 I've try to ask why than threatens to increase this parameter at once large (or make it dependent on RAM): https://lists.freebsd.org/pipermail/freebsd-hackers/2016-November/050142.html but there are no answer options. At the moment, on r315141 boot via UEFI is fine with default EFI_STAGING_SIZE (64) With EFI_STAGING_SIZE=768 i got panic after recent changes with follow message: failed to allocate staging area:9 failed to allocate stating area Failed to start image provided by ZFS (5) I believe that there mfsroot may be greater than 64MB soon or later. Also there are no problems with loading big mfsroot images when MBR method is used. PS: I have ZFS-on-root system. With EFI_STAGING_SIZE=768 I lived with constant CURRENT svnup/rebuilds for about a year. So I will be glad if you pay attention to this. How to reproduce: 1) EFI_STAGING_SIZE=768 in /etc/make.conf 2) make -C /sys/boot clean 3) make -C /sys/boot 4) make -C /sys/boot install 5) reboot Host: FreeBSD 12.0-CURRENT r315413 amd64 -- You are receiving this mail because: You are the assignee for the bug.help
