Hello all-

I'm able to reproduce an oops in 1.3.100. I'm trying to add another hard
drive (Maxtor 7540AV) to my dtc2278EB disk controller (on ide1). I hooked up
the ribbon cable and power cord, booted and got this: (I wrote this down...)

hdc: Maxtor 7540AV, 515MB w/32kb cache, LBA, CHS = 1046/16/63
hdc: IRQ probe failed
hdc: IRQ probe failed
hdc: IRQ probe failed
ide0 at 0x1f0 - 0x1f7, 0x3f6 on irq 14

Current -> tss.cr3 = 00101000, %cr3 = 00101000

started kswapd

and then the machine hangs. This happened 3 times in a row. I'd look up the
EIP value, but ksymoops segfaults and 'nm vmlinux | sort | less' says it
doesn't recognize the file format... :\
