Hi,
I just updated my sources from Nov 30 to Jan 12, and I'm having
kernel panic problems when I try to use the in-kernel pppoe (which had
been working fine for me previously).
After building a new kernel, and rebuilding pppoectl I got my pppoe
session established and then my machine froze solid.
After rebooting, I tried bringing up pppoe again and this time I got a
panic:
amap_wipeout: corrupt amap
amap_wipeout()
amap_unref()
uvm_unmap_detach()
uvmspace_free()
uvm_exit()
reaper()
I updated my kernel sources to todays and tired again. Once the
connection came up, I tried pinging www.yahoo.com and in about 2
seconds I got:
page fault in pmap_change_attrs+0xba
genfs_putpages()
VOP_PUTPAGES()
ffs_full_fsync()
ffs_fsync()
VOP_FSYNC()
ffs_sync()
sync_fsync()
VOP_FSYNC()
sched_sync()
So now I'm back to using the rppppoe package instead of the in-kernel one
and it appears to be working fine. Any idea what could be causing theese
problems, or where I should look further?
Thanks,
Rick
