Subject2.0.33: non-fatal oops in copy_thread
Hi!

There was a non-fatal oops in copy_thread some minutes ago:

Unable to handle kernel NULL pointer dereference at virtual address c0000000
current->tss.cr3 = 00101000, 
*pde = 00102067

This is genuine 2.0.33 on a i486/100, ASUS SP3G, 48 MB, SpeaMirage P64,
NCR 810, Soundblaster 16 running RedHat 5.0 (all updates applied).

The kernel was compiled with gcc 2.7.2.3 with the following config
options:

CONFIG_EXPERIMENTAL=y
CONFIG_MODULES=y
CONFIG_KERNELD=y
CONFIG_NET=y
CONFIG_PCI=y
CONFIG_PCI_OPTIMIZE=y
CONFIG_SYSVIPC=y
CONFIG_BINFMT_AOUT=m
CONFIG_BINFMT_ELF=y
CONFIG_BINFMT_JAVA=m
CONFIG_KERNEL_ELF=y
CONFIG_M486=y
CONFIG_BLK_DEV_FD=m
CONFIG_BLK_DEV_LOOP=m
CONFIG_INET=y
CONFIG_IP_NOSR=y
CONFIG_SKB_LARGE=y
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_CHR_DEV_ST=m
CONFIG_BLK_DEV_SR=m
CONFIG_CHR_DEV_SG=m
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_NCR53C8XX=y
CONFIG_SCSI_NCR53C8XX_NVRAM_DETECT=y
CONFIG_SCSI_NCR53C8XX_TAGGED_QUEUE=y
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=4
CONFIG_SCSI_NCR53C8XX_SYNC=5
CONFIG_NETDEVICES=y
CONFIG_DUMMY=m
CONFIG_PPP=m
CONFIG_NET_ETHERNET=y
CONFIG_NET_ISA=y
CONFIG_NE2000=m
CONFIG_MINIX_FS=m
CONFIG_EXT2_FS=y
CONFIG_FAT_FS=m
CONFIG_MSDOS_FS=m
CONFIG_VFAT_FS=m
CONFIG_PROC_FS=y
CONFIG_NFS_FS=m
CONFIG_SMB_FS=m
CONFIG_SMB_WIN95=y
CONFIG_ISO9660_FS=m
CONFIG_AUTOFS_FS=m
CONFIG_SERIAL=y
CONFIG_PRINTER=m
CONFIG_SOUND=y

The oops happened when I was reading a message in a pine. gcc was
rebuilding the gnome-0.12 rpm in the background. X was not running
as I was working in the console. It seems gpm died during the oops
and it even won't restart.

If there is anything I can do to help tracking down this bug please
mail me.
