Hello,
I'm experiencing a kernel panic that appears to be caused by zfs.
No errors are making it into /var/log/messages, but here is the error
message that appears on my screen after panic (transcribed):
panic solaris assert BSWAP_32(sa_hdr_phys->sa_magic) == SA_MAGIC,
file: /src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/sa.c, line 1262
I can reproduce this by running "cd /usr/ports/www/webkit-ghtk2; make
clean"
I looked at line 1262 in sa.c and it's part of a bit of code that checks
if byte swapping is necessary. The code starting at line 1260:
if (IS_SA_BONUSTYPE(bonustype) && sa_hdr_phys->sa_magic != SA_MAGIC &&
sa_hdr_phys->sa_magic != 0) {
VERIFY(BSWAP_32(sa_hdr_phys->sa_magic) == SA_MAGIC);
sa_byteswap(hdl, buftype);
}
As far as I can tell, my source is up to date and this code is the same
as what is in 9-STABLE.
I'm not sure what's causing the panic, does anyone have a suggestion?
Thanks for the help.
