Subject.97 hates me
I've had very good success with almost every kernel in the 1.3 series, but
for some reason .97 really does NOT seem to like me. Perhaps I have abused
penguins in a previous life or something.

With .97 running (module support enabled, but not using the module daemon),
I get oopses frequently that look like these:

...then the whole system will lock solid, requiring a BRS massage to recover.

This is the stuff that is turned on in .config:

CONFIG_MODULES=y
CONFIG_NET=y
CONFIG_PCI=y
CONFIG_PCI_OPTIMIZE=y
CONFIG_SYSVIPC=y
CONFIG_BINFMT_AOUT=y
CONFIG_BINFMT_ELF=y
CONFIG_KERNEL_ELF=y
CONFIG_M586=y
CONFIG_BLK_DEV_FD=y
CONFIG_BLK_DEV_LOOP=y
CONFIG_INET=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_CONSTANTS=y
CONFIG_SCSI_AIC7XXX=y
CONFIG_NETDEVICES=y
CONFIG_PPP=y
CONFIG_MINIX_FS=y
CONFIG_EXT2_FS=y
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_PROC_FS=y
CONFIG_ISO9660_FS=y
CONFIG_SERIAL=y
CONFIG_PRINTER=y
CONFIG_SOUND=y

I tried to use ksymoops on it, but it segfaulted ;-)

With the same .config, the system is completely stable under 1.3.96 and
earlier, but all hell breaks loose with .97.
