Since GEOM became default, I've been getting a lot of errors like these:
Oct 9 17:02:19 uriel kernel: swap_pager: I/O error - pageout failed; blkno
3240
,size 4096, error 5
Oct 9 17:02:19 uriel kernel: swap_pager: I/O error - pageout failed; blkno
1254
4,size 8192, error 5
Oct 9 17:02:19 uriel kernel: swap_pager: I/O error - pageout failed; blkno
1257
6,size 8192, error 5
These seem to go away when the kernel is built with NO_GEOM.
I added a panic just below this message in swap_pager.c - backtrace attached.
I haven't really looked at it yet and I won't be able to use this machine for
a few hours. Any assistance appreciated.
