That's pretty much been my experience. 2.2.10 crashes on a regular basis. Certainly more than previous kernels. Why? Who's to say? It leaves behind no information. Nothing in the logs, nothing in dmesg (which changes with each boot up, anyhow). There's no way to try the magic SysRq key, as the keyboard is completely locked up. I can't telnet/ssh/ftp/ping the box, as it evidently stops processing all network requests. In short, there is absolutely no indication, not the slightest oops or byte left over, to even begin to give the inkling of a clue about why the system crashed. So how do you debug that? I don't even know how to cause the crash; usually i get up in the morning, or come home from work, to find the machine all locked up.
This particular machine is an AMD K6-2/350 *not* OC'ed, 64M Ram, Asus P5A mobo, Buslogic BT-932 with a 4.5 Seagate, 24x Panasonic, and a JVC 2010 clone CDR, with a NetGear FA310TX (new one) nic, and an SiS 6326 video card. I use Redhat 6.0, fixed. Currently, I have X (SVGA), Window Maker 0.60.0 (I upgraded, in case it was WM causing lockups), Samba 2.0.4b, knfsd 1.3.2, and my gnome is custom compiled.
OTOH, my masq machine doesn't crash. It's a little 486/120 w/32M Ram, mobo unknown, running a D-Link 220 NIC, an SIIG (Promise chipset) EIDE controller card, an Orchid Fahrenheit video card (rarely used), and a Zoom modem. With the exception or X programs, it's got the same software as my workstation, RH 6.0, samba, knfsd, etc. Just no X.
I suffer, and hope that 2.2.11 will solve my problems with my WS. -- Matthew Vanecek Course of Study: http://www.unt.edu/bcis Visit my Website at http://people.unt.edu/~mev0003 For answers type: perl -e 'print $i=pack(c5,(41*2),sqrt(7056),(unpack(c,H)-2),oct(115),10);' ***************************************************************** For 93 million miles, there is nothing between the sun and my shadow except me.
