Afternoon Gents (and Ladies),
I'm setting an interesting problem with the sata_svw driver on a fairly
new (in terms of model) blade server from HP, a BL495c.
[ 3.462135] PCI: setting IRQ 14 as level-triggered
[ 3.462142] sata_svw 0000:01:0e.0: PCI INT A -> Link[ISF0] -> GSI 14
(level,
low) -> IRQ 14
[ 3.465367] sata_svw 0000:01:0e.0: PCI INT A disabled
[ 3.467302] sata_svw: probe of 0000:01:0e.0 failed with error -16
Having trouble tracking down what 'error -16' might imply, any pointers
for what the root cause may be and how to address it?
Regards,
Alex

I should have noted this happens in the latest -stable and the problem
appears to persist if I go back a couple of versions to 2.6.25, etc.
Kernel config is over at:
http://havok.aeode.net/~ahowells/2.6.27.7-config
Cheers,
Alex

That's the EBUSY error (include/asm-generic/errno-base.h).
What kernel? I don't see a 'probe of ... failed' message in drivers/ata
nor drivers/pci.

It's running on 2.6.27.7 at the moment...
