Some weeks ago I posted about a panic in 5.2-BETA. After accessing a read-only ext2fs for some hours I got a "page fault" panic (or rarely a "getblk: size(7537385) > MAXBSIZE(65536)"). The backtrace was always somewhat different. You can read about it a bit more detailed here: http://lists.freebsd.org/pipermail/freebsd-current/2003-November/015405.html After lots of buildworld and buildkernel I finally was able to detect the commit that caused this panic. Current from 2003.11.09.09.00.00 runs fine for > 10 hours. Current from 2003.11.09.09.20.00 crashed twice within less than 2 hours. The only src/sys commit in that time is http://lists.freebsd.org/pipermail/cvs-src/2003-November/013515.html where selwakeup()s is replaced with selwakeuppri(). So the problem must be somewhere in selwakeuppri(). I hope this can be resolved now.
