Hi, I get occasional crashes with 4.0. The server AMD2800+ 1Gig RAM, Ext3 with the latest yum update. Happened after large file transfers [500Mb+] The error is: Kernel: Assertion failure in __journal_file_buffer at fs/jbd/transaction.c 1947: "jbd_is_locked_bb_state(bh)" The computer freezes, the lights on the keyboard flashes. Nothing responds, only pressing the reset button works. I have CentOS4 installed on this one [that crashes], on my laptop [no problem] and a couple of other servers without any problem. Could this be hardware related? What can I do about it? Any suggestion? Thanks
