I just upgraded from 2.2.16 to 2.2.18 in a production machine. The machine dies after few minutes with the following error message (it's not complete, the machine was rebooted by a colleague of mine): Kernel panic Exception. Context corruption at bank 0 The motherboard is a RD440LX DP, with adapted 2940, 3com905, mtrr enabled, ioapic enabled. We've tried several times with the same kernel and we've got the same problem after a couple of minutes. Sometimes the machine was completely blocked, even ping didn't work, others ping was ok but everythng else was down. Sysrq couldn't sync nor unmount disks. We went down to 2.2.16 and everything it's ok. Hope this helps.
