This seems to occur more often the smaller the used font and/or the larger the xterm is, or better the more amount to scroll. This also happened from time to time under 1.1.5.1 and was one of the reasons i wanted to upgrade. When this happens, the machine is totally frozen so there is not even a chance to look from another side into the machine. 2) Disk i/o hangs, sometimes with the access LED on the controller on, some- times off. The machine is operational as long as one does not "touch" the disks, so i would be able to search for something if someone would tell me where to search and what to search for. 3) lpt0 is sometimes not found, sometimes it is found during probe. It was always found under 1.1.5.1. The machine is a 486DX2 EISA machine manufactured by Kyocera: FreeBSD 2.0.5-RELEASE #0: Tue Jul 18 22:07:24 MET DST 1995 root@ernie.altona.hamburg.com:/usr/src/sys/compile/ERNIE CPU: i486 DX2 (486-class CPU) Origin = "GenuineIntel" Id = 0x435 Stepping=5 Features=0x3 real memory = 16384000 (4000 pages) avail memory = 14864384 (3629 pages) Probing for devices on the ISA bus: ed0 at 0x300-0x31f irq 10 maddr 0xcc000 msize 16384 on isa ed0: address 00:00:c0:ea:7e:65, type WD8013EPC (16 bit) bpf: ed0 attached vt0 at 0x60-0x6f irq 1 on motherboard vt0: s3 928, 80/132 col, color, 8 scr, mf2-kbd, [R3.30] sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A sio2 at 0x3e8-0x3ef irq 5 on isa sio2: type 16550A sio3 at 0x2e8-0x2ef irq 7 on isa sio3: type 16450 lpt0 not found at 0xffffffff fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 72065B fd0: 1.44MB 3.5in fd1: 1.2MB 5.25in ahb0: reading board settings, int=11 ahb0 at 0x4000-0x40ff irq 11 on eisa slot 4 (ahb0:0:0): "QUANTUM MAVERICK 540S 0901" type 0 fixed SCSI 2 sd0(ahb0:0:0): Direct-Access 516MB (1057758 512 byte sectors) sd0(ahb0:0:0): with 2853 cyls, 4 heads, and an average 92 sectors/track (ahb0:1:0): "QUANTUM LPS540S 5900" type 0 fixed SCSI 2 sd1(ahb0:1:0): Direct-Access 516MB (1057616 512 byte sectors) sd1(ahb0:1:0): with 2740 cyls, 4 heads, and an average 96 sectors/track (ahb0:2:0): "MICROP 2112-15MQ1086403 HQ48" type 0 fixed SCSI 2 sd2(ahb0:2:0): Direct-Access 1001MB (2051615 512 byte sectors) sd2(ahb0:2:0): with 1760 cyls, 15 heads, and an average 77 sectors/track ahb1: reading board settings, int=12 ahb1 at 0x5000-0x50ff irq 12 on eisa slot 5 (ahb1:5:0): "TOSHIBA CD-ROM XM-3401TA 2873" type 5 removable SCSI 2 cd0(ahb1:5:0): CD-ROM cd present.[264427 x 2048 byte records] (ahb1:6:0): "ARCHIVE VIPER 2525 25462 -011" type 1 removable SCSI 1 st0(ahb1:6:0): Sequential-Access density code 0x0, drive empty npx0 on motherboard npx0: INT 16 interface ups0 at 0xc06 on motherboard ups0: Kyocera EP7000 UPS driver 1.20, status byte = 0x2d ups0: - battery was full at power-up time ups0: - battery is currently empty ups0: - system running from AC power bpf: lo0 attached bpf: tun0 attached bpf: tun1 attached If i didn't had this symptoms, it were a really nice OS, very very well done, core team !!! hellmuth -- Hellmuth Michaelis hm@altona.hamburg.com Hamburg, Europe (A)bort, (R)etry, (I)nstall BSD ?
