freebsd stable - Aug 2003 - Ok, are all the panics fixed now? )

Hi All,

In a 4.9-PRERELEASE kernel, enabling PAE panics Highpoint Raid module 
(hpt374.ko)


I preload the module, and during boot I see a panic when it attempts to
initialise.  100% reproducible. The panic seems to happen in
pmap_kthread... (mumble) ... I got this from a ddb 'trace' command.


During normal operations I see that it has installed itself as some kind
of kernel thread - don't know the precise terminology for this, but ps
ax says -

    0  ??  DLs    0:00.00  (swapper)
    1  ??  ILs    0:00.08 /sbin/init --
    2  ??  DL     0:00.00  (usb0)
    3  ??  DL     0:00.00  (usbtask)
    4  ??  DL     0:04.56  (usb1)
    5  ??  DL     0:00.00  (pagedaemon)
    6  ??  DL     0:00.00  (vmdaemon)
    7  ??  DL     0:00.00  (bufdaemon)
    8  ??  DL     0:00.01  (vnlru)
    9  ??  DL     0:00.19  (syncer)
   10  ??  DL     0:00.00  (hpt374)


Without PAE the Highpoint driver is rock solid.

Cheers,

Andrew.

PAE option changes the ABI between the kernel and a module, so you need
to recompile the module from source with PAE option enabled. The driver
also has to be able to handle physical memory above 4G, either the
hardware can address 64bit directly or through bounce buffers below 4G
(via the bus_dma facility).
