Probably why my Pentium-III 866 locks up (with a continuous beep from the PC speaker) when I switch virtual consoles (no X running) when doing disk I/O and one console is running the standard 80x25 and the other is running 132x60. Seems to happen every time so far and has done so for several months. It doesn't happen on my Celeron 450 Slot-1 (actually a 300a running at 100Mhz FSB instead of 66MHz) with an Nvidia TNT2 16MB, Western digital something 20GB also using 80x25 and 132x60. (also GENERIC kernel and v.new -CURRENT). The P-III 866 has an Nvidia GeForce2 MX400 64MB, IBM 120GXP 40GB drive, very new -CURRENT and GENERIC kernel. extract of /boot/loader.conf has: hw.ata.wc="1" hw.ata.tags="1" <----------- This line not on the Celeron 450 box as vesa_load="YES" the WD drive cant do tagged command queing extract of /etc/rc.conf has: font8x16="cp437-8x16.fnt" font8x14="cp437-8x14.fnt" font8x8="cp437-8x8.fnt" -- Matthew Thyer Phone: +61 8 8259 7249 Science Corporate Information Systems Fax: +61 8 8259 5537 Defence Science and Technology Organisation, Edinburgh PO Box 1500 EDINBURGH South Australia 5111 IMPORTANT: This email remains the property of the Australian Defence Organisation and is subject to the jurisdiction of section 70 of the CRIMES ACT 1914.
