Hello Alan,

   I have a UMSDOS system with egcs v1.1.2 and libc 5.3.12. My hardware
is a Dell 333mhz GX1 with scsi U2W (AIC 7895) and 128 megs of memory.
I don't have any swap turned on.
Here is a list of the problems with the linux v2.2.21 pre releases:

v2.2.21pre2      boots and works ok.
v2.2.21pre3      filesystem panic after root mounted and umssync is run.
v2.2.21pre4      hangs on boot after the message
		 "Intel machine check architecture supported"

v2.2.21rc1       Oops' on boot after the message "CPU: L2 cache = 512K
                 with a kernel panic. Note: I don't have any swap turned on.
