Booted into linux 2.2.18 and everything is fine. Together with the events of freezing in pine I would suggest that there is something in the kernel scribbling memory. I am back to 2.2 for good for now. Two issues: * __alloc_pages can get into a "dead lock" situation. Please se my: "[PATCH] test9: another vm lockup bug - squashed" * it refers to Riels patch of freepages With these additions you get more pages free - less likely not to block on read (really: cp disk CD) If this does not help consider trying Andrew Mortons "lowish-latency patch for 2.4.0-test9" * It avoids getting stuck in kernel loops when the CPU is better needed for some other process. /RogerL -- Home page: http://www.norran.net/nra02596/ -- Home page: http://www.norran.net/nra02596/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
