Why would system time not be adjusted to the PTP time?
This is my main concern, that we're presenting a fractured API to
userland. Suddenly there isn't just system time, but ptp time as well,
and possibly multiple different ptp
Hi,
My system is MPC870 based and I'm enabling the I2C driver and the
ds1339 RTC driver. When the kernel tries to probe the RTC chip (slave
address 0x68), the first write seems OK but the subsequent read times
out. I applied the I2C/SPI microcode patch, which doesn't seem
necessary though. Below

Hi,
Thanks for all your replies. Now I want to enable interrupts on some GPIO
pins(GPIO pins number 224, 225, 226, 227, 228 and 229 i.e gpiochip224's pins
0 to 5). I configured these pins as input(GPIOF_IN) during gpio request. I
am able to request gpio pins successfully.

Clear the machine check syndrom register before enabling machine check
interrupts. The initial state of the tlb can lead to parity errors being
flagged early after a cold boot.

Josh,
Here are some bug fixes for the powerpc-4xx tree. It'd be nice if they
could make it into 2.6.46.
Thanks,

The interrupt stacks need to be indexed by the physical cpu since the
critical, debug and machine check handlers use the contents of SPRN_PIR to
index the critirq_ctx, dbgirq_ctx, and mcheckirq_ctx arrays.

The dlpar code can cause a deadlock to occur when making the RTAS
configure-connector call. This occurs because we make kmalloc calls,
which can block, while parsing the rtas_data_buf and holding the
rtas_data_buf_lock. This an cause issues if someone else attempts

Similar here, but using atomic_long_t instead so it works for 32-bit too
