Well stone the bloody crows. System: HP Kayak XA 440BX M/b, P-II, Quantum Fireball ex4.3a
For months I've been running with no flags on either wdc0 or wd0. Having followed the recent discussions about DMA mode etc I looked at LINT and added "flags 0xa0ff" to wd0. Rebuilt the system using the latest 3-Stable code, including Matt D.s VM fixes, and tried yet again the test that has quite reliably frozen my system (softupdates enabled on /usr/src, cd /usr/src/games, make) and, lo and behold, it worked. I thought it was probably Matt's VM patches but (just to make sure) I built a kernel without the wd flags and tried again. It failed. This seems to be saying the problem is the WD driver: When I have flags on my disk, it all works; when I use the default, it fails (but only on filesystems with softupdates activity...) Any ide_pci experts like me to try some more tests? Matt: I'm sorry I ever doubted the VM code or the softupdates!
