Please post the version of the OS.

Your "Cannot dump 524190 pages to dumpdev hd (1/41)" errror is just lack of space to create the dump - only 128000 was available - that isn't your problem with your system.

Your problem is associated with this error:
Panic: HTFS: Bad directory ino 2 (offset 0) on HTFS hd (1/169)

That is what caused your system to crash (and attempt to create a crash dump)

This info on booting single user and filesystem checks may help.
