i have seen the screen white out and belive it is related to masive poower draw (ie a bug in the firmware) that knocks out the screen, it would also explain the resets and why everything keeps working when you pull it out
however i have no proof
I recently purchased a new AmbiCom WL1100C-CF and I'm experiencing similar problems:
- screen fades to white, unplugging card returns screen
- Zaurus sometimes bogs down, becoming extremely slow to respond while card is inserted
- card will shutdown intermittently for no reason
- card generates significantly more heat than the Symbol LA-4137 it is replacing
- battery runs down much more quickly than with Symbol card
I've found a couple posts where people suggest that it may be an issue with excessive power draw. I've also read people make vague complaints about both the "new" firmware being buggy and the "old" firmware being buggy. I don't know which firmware might work!
When I run hostap_diag, I got the following:NICID: id=0x801b v1.0.0 (PRISM III PCMCIA (SST parallel flash))
PRIID: id=0x0015 v1.1.1
STAID: id-0x001f v1.8.0 (station firmware)
I assume the v1.8.0 is my firmware. In mikeones' post, he claims to be using 1.7.4 and is having the same problem. Is there a stable firmware version that someone would recommend?
Another thing I noticed was some apparent inaccuracy with the data that cardctl is returning. I don't know if status and control are supposed to match, but the Vcc data that cardctl config is returning seems to be corrupt. I get a similar result with my Symbol card, but my wired CF NIC is showing Vcc=0.0V (which also seems wrong).root> cardctl status
3.3V 16-bit PC Card
function 0: [ready]
root> cardctl config
251354149570021102190592.0V Vpp1 0.0V Vpp2 0.0V
interface type is "memory and I/O"
irq 135 [exclusive] [level]
config base 0x03e0
io 0xf6000000-0xf600003f [16bit]
Since my old Symbol card works, I'm assuming it's a firmware issue with the AmbiCom, but is the cardctl data possibly contributing to the problem? Or is it possible that this card is defective and should be returned? It seems that the problem is actually getting worse.
