Running vidfont again changed every character up through 'w' or 'x' (lower case w or x). I noticed since I have a lower case 'z', a lower case 'y', which were the original font at boot, and a 'v' which was the installed iso-thin-8x16. Running vidfont yet again completed changing the screen font. Then, I happened to bump the mouse, and got a 'page fault in kernel mode' or whatever that message is... and a core dump... backtrace with gdb -k on the core dump shows: #0 0xf010d6a3 in boot () #1 0xf010d962 in panic () #2 0xf0180236 in trap_fatal () #3 0xf017fd24 in trap_pfault () #4 0xf017f9ff in trap () #5 0xf012cb46 in vget () #6 0xf01616cc in ffs_sync () #7 0xf012dffb in sync () #8 0xf010d56d in boot () #9 0xf010d962 in panic () #10 0xf0180236 in trap_fatal () #11 0xf017fd24 in trap_pfault () #12 0xf017f9ff in trap () #13 0xf019f8e0 in draw_mouse_image () #14 0xf019b65d in scrn_timer () #15 0xf0104b74 in softclock () >How-To-Repeat: I don't know, the first problem (vidfont failing to change all the characters when it changes the font) has only happened to me three times, at intervals greater then 4 months apart. The other two times, I didn't have a swap partition big enough to contain a crash dump, so I don't know exactly where they crashed (this time, the IP given on the crash screen corresponded to the vget() call above, address was: 0x8:0xf012cb46). >Fix: >Audit-Trail: >Unformatted:
