I have tried bootx 1.1 and 1.1.1 as well as numerous kernels with support for the ncr (ATTO) UW card. I have tried vmlinux4, and several of the kernels from skinnydesign. I have yet to find a stable combination. I am beginning to believe that I have a hardware problem. I replaced my keyboard and mouse cables (explanation in a moment), removed (and switched) ram from the machine and disconnected all other peripherals. The problem I am having is the machine kernel panics either during the boot sequence (right as it's probing the UW drive or during the first few min of operation (usually not more than five min). Somtimes, however, I can keep it running for a while, but that is only if I don't move the mouse or type anything (hence changing the cables...I also switched keboards and mice, to no avail) The kernel panic is allways the exactly the same regardless of how long the machine is up or when it panics (at boot or after) and I was wondering if anyone could shed some light as to what may be the problem. I am thinking of buying a 2940UW hoping that will fix the problem but I wanted to get some feed back from someone who may could help diagnose the problem so I don't waste my money. An exerpt of the message is: machine check trap: 0200 Task=C0181fd8[0] 'swapper' mm->pgd C017f000 LAst sys call: 112 Last Math: c5dc000 call backtrace C01A0000 C00003A80 C001C6FC C0005AB4 C0005ADC C000388C 0C0B53D0 Kernel panic - swapper task not syncing This has to be one of the most frustrating things I have ever dealt with with linux. Just as soon as I think I have the problem fixed....it boots, I log in and type for a couple of min or click on a window and *crash* , never more than 10 min use. If anyone could give me a hand, especially those with similar machines (how long does everyone elses 333/UW stay up?) I would be eternally gratefull. I have some work I need to do with this machine and I would really like to do it with Linux.
