Our machine: Siemens Celsius 620 Dual-P3 (disabled SMP for testing, problem didn't go away), 256MB RAM, aic7xxx (7895, I think, TCQ enabled); Kernel 2.2.12, applied raid0145-19990824-2.2.11 patch (ignored fs.h warning), raidtools-19990824-0.90. Our problem: When I mkraid /dev/md0 (raid1), things initially seem to work fine, but cat /proc/mdstat says ...finish=xxx m with xxx rapidly INCREASING. (Many minutes per second.) A short time afterwards, the machine hangs. Any idea, anyone? -- regards, [EMAIL PROTECTED] (o_ Thomas Fischbacher - http://www.cip.physik.uni-muenchen.de/~tf //\ (lambda (n) ((lambda (p q r) (p p q r)) (lambda (g x y) V_/_ (if (= x 0) y (g g (- x 1) (* x y)))) n 1))
