I don't know if it is at all related, but this commit has caused problems for me booting at least one of my machines: http://svn.freebsd.org/viewvc/base/head/sys/boot/i386/zfsboot/zfsboot.c?r1=199714&r2=200309 Commit message: Revision 200309 - (view) (annotate) - [select for diffs] Modified Wed Dec 9 20:36:56 2009 UTC (2 months, 2 weeks ago) by jhb File length: 24893 byte(s) Diff to previous 199714 - Port bios_getmem() from libi386 to {gpt,}zfsboot() and use it to safely allocate a heap region above 1MB. This enables {gpt,}zfsboot() to allocate much larger buffers than before. - Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers. This allows more reliable reading of compressed files in a raidz/raidz2 pool.
