Info: I just replaced the root file-system, utilities, and kernel in an old '386SX (16MHz). Compiled with math emulation, etc.
The machine boots, mounts the file-system (will even do the e2fsck).
As soon as I log in (which works), and do:
# cd /etc # ls
I have done this several times. It is repeatable. If I do anything that makes the 'bell' sound, or if the machine is idle for more than a few seconds, it will halt foerver.
The machine will hang. No interrupt activity whatsoever. Looking at IRQ0 (timer-tick) on the bus shows it permanently high. Perhaps these old machines can't use level-triggered interrupts. It worked with an old version of Linux for several years. It still worked before I installed 2.1.42. The old version was 0.99 (Yaggdrasl). Now I am gonna be in trouble with the owner (an executive).
I will probably have to give him a "new" motherboard with a '486-DX/66 to get him off my back (I have a old spare).
This is the configuration.
CONFIG_MODULES=y CONFIG_MATH_EMULATION=y CONFIG_NET=y CONFIG_SYSVIPC=y CONFIG_SYSCTL=y CONFIG_BINFMT_AOUT=y CONFIG_BINFMT_ELF=y CONFIG_M386=y CONFIG_VIDEO_SELECT=y CONFIG_BLK_DEV_FD=y CONFIG_NET_ALIAS=y CONFIG_INET=y CONFIG_PATH_MTU_DISCOVERY=y CONFIG_IP_NOSR=y CONFIG_SKB_LARGE=y CONFIG_SCSI=y CONFIG_BLK_DEV_SD=y CONFIG_CHR_DEV_ST=y CONFIG_BLK_DEV_SR=y CONFIG_SCSI_AHA1542=y CONFIG_NETDEVICES=y CONFIG_NET_ETHERNET=y CONFIG_NET_VENDOR_3COM=y CONFIG_EL2=y CONFIG_EL3=y CONFIG_PPP=y CONFIG_EXT2_FS=y CONFIG_FAT_FS=y CONFIG_MSDOS_FS=y CONFIG_VFAT_FS=y CONFIG_PROC_FS=y CONFIG_NFS_FS=y CONFIG_NFSD=y CONFIG_SUNRPC=y CONFIG_LOCKD=y CONFIG_ISO9660_FS=y CONFIG_VT=y CONFIG_VT_CONSOLE=y CONFIG_SERIAL=y
I would suggest that support for '386s be disabled sometime soon, i.e., disable math emulation so that folks don't think that their old clunkers will work with the new kernels.
