>Environment:
Abit KT7-RAID motherboard with HPT370 RAID chipset. Two identical model
IDE drives, each on a seperate IDE channel. Using a slightly modified
ata-raid.c to compensate for the HPT370's need to store RAID data in block
9(10?). That modification is the adding of "if (buf1->drive)" before
"buf1->bp.b_pblkno += rdp->offset;"
>Description:
The system kernel panics approximately 2 minutes after a drive in the
array fails/disappears. Expected behavior would be for it to keep
attempting to access the drive for a while, then give up on it and
continue running off the remaining drives in the array.
Panic messages:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x68
fault code = supervisor read page not present
instruction pointer = 0x8:0xc0166e2c
stack pointer = 0x10:0xc02810d4
frame pointer = 0x10:0xc0281104
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = Idle
interrupt mask = bio
trap number = 12
panic: page fault

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x30
fault code = supervisor read page not present
instruction pointer = 0x8:0xc0202b74
stack pointer = 0x10:0xc0280f04
frame pointer = 0x10:0xc0280f08

panic: page fault
>How-To-Repeat:
Install a 4.2-RC1 system onto an ar* RAID 1 array using the HPT370 chipset
(found on the Abit KT7-RAID motherboard). Disconnect power to one of
drives. System will panic within about 2 minutes.
