- Count the number of this error.
- When the error is detected for the first time, the psm driver will
throw few data bytes (up to entire packet size) and see if it can
get back to sync.
- If the error still persists, the psm driver disable/enable the mouse
and see if it works.
- If the error still persists and the count goes up to 20,
the psm driver reset and reinitialize the mouse. The counter
is reset to zero.
- It also discards an incomplete data packet when the interval
between two consequtive bytes are longer than pre-defined timeout
(2 seconds). The last byte which arrived late will be regarded as
the first byte of a new packet. This is louie's idea.
You may see the following error logs during the above operations:
"psmintr: delay too long; resetting byte count"
"psmintr: out of sync (%04x != %04x)"
"psmintr: discard a byte (%d)"
"psmintr: re-enable the mouse"
"psmintr: reset the mouse"

free. Previously contigfree() freed up the KVA space but could not
unwire & free the underlying VM pages due to mismatched pageability between
the map entry and the VM pages.

would sometimes prevent a dirty page from being cleaned, even when synced,
resulting in the dirty page being re-flushed to disk every 30-60 seconds or
so, forever. The problem is that when the filesystem flushes a page to
its backing file it typically does not clear dirty bits representing areas
of the page that are beyond the file EOF. If the file is also mmap()'d and
a fault is taken, vm_fault (properly, is required to) set the vm_page_t->dirty
bits to VM_PAGE_BITS_ALL. This combination could leave us with an uncleanable,
unfreeable page.
The solution is to have the vnode_pager detect the edge case and manually
clear the dirty bits representing areas beyond the file EOF. The filesystem
does the rest and the page comes up clean after the write completes.

o Remove the whois.networksolutions.com fallback code, which is no

o Instead of determining a hostname by terminating it when we see
whitespace, only allow hostname characters and terminate the string
when it's not such a character.
