hello everyone, i am really weirded out by some of the messages that appear on stdout from syslog and the kernel. i dunno where to turn in order to interpret the messages so i ask if you please take a look.. and perhaps direct me to someone. thank you in advance im setting up a pc that i want to use as server. its characteristics are m/b: Gigabyte - GA965P -DQ6. Northbridge: Intel P965 chipset; Southbridge: Intel ICH8R chipset; supports 6x Sata2 drives in; simple, AHCI, or raid 0,1,5,10,JBOD Gigabyte Sata controller; an additional controller (dunno what driver goes with it in linux kernel) supports 2 additional sata2 ports and raid 0,1 configurations. also: 1x WD 40GB raptor hard drive for the OS and 4x 320GB caviar hard drivers in RAID5 for data. ok i have setup the raid5 and i think it is working fine - it is not of much interest anyway.. i just note it in case you know of smth that is slipping me... also im running slackware 11. with a kernel that compile on my own from v. 2.6.20.7 the important and the reason im writing , is cause im trying to download some files from another pc through an sftp session.. im saving to the 40GB drive. thats /dev/sda1. the name of the pc is 'stargaze' .. now some history: last night twice in trying to copy a big tar.bz2 (100MB) from that pc to stargaze. and at some point it froze ( the pc that is). so i restarted and redid the sftp session.. the file arrived. then i also tried to download with mget ... about 200 photos of size 1MB each. the pc crashed again (btw not even reset button would restart the pc). reboot the pc.. (it took ages cause it would find that the file system is NOT clean and it would initiate 'journal transactions'. ok well that message was perhaps intented for sda1.. but its possible it was for /dev/md0.... anyhow today i tried again the same 2 sftp sessions.. trying to download the same files... it worked the couple of times i tried it... but here is the weird messages im getting... on stdout and /var/log/syslog BUG: unable to handle kernel paging request at virtual address 6dcecdd9 printing eip: c02eb417 *pde = 00000000 Oops: 0000 [#1] SMP Modules linked in: snd_seq_dummy
