Freeze or reboot issue by receiving bytes on /dev/ttyBF0

Hello everybody, I hope I post on the right mailling list :

I have a BF537 board where I need to use /dev/ttyBF0 to connect a GPRS 
modem (/dev/ttyBF1 is already used for a GPS).
To have /dev/ttyBF0 available under uClinux, I deactivate the console 
this way in uboot with the "console" kernel option : console=null
But I experience freeze or reboot and I understood when it happens : 
it's when one or more byte arrives on the serial port and the 
/dev/ttyBF0 port is not opened by any process.

Anybody experienced this issue too ? Is there a workaround or do I need 
to analyse the uClinux-dist/linux-2.6.x/drivers/serial/bfin_5xx.c to try 
to unsertand the problem ?

Best regards,
Cyril HAENEL

[PATCH net-next] drivers:net: Remove unnecessary OOM messages after netdev_alloc_skb

Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM
messages is unnecessary as there is already a dump_stack
after allocation failures.

Other trivial changes around these removals:

Convert a few comparisons of pointer to 0 to !pointer.
Change flow to remove unnecessary label.
Remove now unused variable.
Hoist assignment from if.

[PATCH 1/2] musb: framework: add bf60x support

This patch makes musb framework can support blackfin bf60x series soc platform.
Bf60x uses MHDRC RTL version 2.0 musb ip core which don't need a lot of
blackfin specific anomalies anymore.

[PATCH] bfin_mac: Restore hardware time-stamping dependency on BF518

Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all
dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware
time-stamping is only available on BF518 though. Since the Kconfig entry is
'default y', just updateing your kernel source and running `make defconfig` will
result in the the following build errors:

	drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’
	drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’
	...

This patch adds back the dependency on BF518, and since it does not make sense
to expose this config option when the blackfin MAC driver is not enabled also
restore the dependency on BFIN_MAC.

[PATCH 01/25] ASoC: blackfin: remove __dev* attributes

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

[PATCH] blackfin: use bitmap library functions

The bitmap library provides more efficient functions than accessing
individual bits with bitops.

This uses bitmap_find_next_zero_area() to find a continuing zero area,
and uses bitmap_set()/bitmap_clear() to set/clear specified bit area.
