https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253158 --- Comment #43 from Cy Schubert <cy@FreeBSD.org> --- (In reply to Konstantin Belousov from comment #39) Both patches, each by themselves, don't panic. The sys/ufs/ffs/ffs_snapshot.c patch resolves the problem without causing any other problems. However the sys/kern/vfs_vnops.c patch by itself causes other problems which results in the following errors during boot: mountroot: waiting for device /dev/ada0s1a... input in flex scanner failed read: read error: Unknown error: 66047 warning: total configured swap (524276 pages) exceeds maximum recommended amount (457736 pages).

I cannot continue testing sys/kern/vfs_vnops.c by itself tonight. I can continue tomorrow. Repeat: sys/ufs/ffs/ffs_snapshot.c does fix the problem without any negative effects. -- You are receiving this mail because: You are the assignee for the bug.
