Subject: 2.6.8.1-mm1: oops with firmware loading
Date: Tue, 17 Aug 2004 15:28:18 +0200 [thread overview]
Message-ID: <412207F2.8070404@fh-hagenberg.at> (raw)
Hi,
The new sysfs-backingstore patches cause an oops when I ifup a
prism54 based device, heres the dmesg section:
Loaded prism54 driver, version 1.2
PCI: Enabling device 0000:03:00.0 (0000 -> 0002)
ACPI: PCI interrupt 0000:03:00.0[A] -> GSI 9 (level, low) -> IRQ 9
eth0: no IPv6 routers present
eth2: islpci_open()
eth2: resetting device...
eth2: uploading firmware...

<3>prism54: request_firmware() failed for 'isl3890'
eth2: could not upload firmware ('isl3890')
Backing out all sysfs-backing-store patches cures the problem.
(sysfs-backing-store-prepare-file_perations.patch alone triggers the
oops)
I think the oops comes from
drivers/base/firmware_class.c:423
Thanks,
