Kernel OOPS v7.90.010 ALPHA DVB-USB TT S2-3600

Hello LibreELEC,
I did upgrade to v7.90.010 ALPHA on my RPI 3 the other day.
Now my DVB-USB-TVCard TT S2-3600 is not working anymore.
In dmesq I see a kernel oops.

Code

[    3.242615] dvb-usb: found a 'Technotrend TT Connect S2-3600' in warm state.
[    3.242627] pctv452e: pctv452e_power_ctrl: 1
[    3.242627]
[    3.243989] Unable to handle kernel NULL pointer dereference at virtual address 00000000
[    3.243995] pgd = adb60000
[    3.243997] [00000000] *pgd=00000000
[    3.244006] Internal error: Oops: 805 [#1] SMP ARM
[    3.244026] Modules linked in: dvb_usb_pctv452e(+) ttpci_eeprom dvb_usb dvb_core rc_core

In 7.03 this card was recognized.

Thanks for the great work btw!
Cheers,
vchief

Same with 7.95.1. Can't provide dmesg as paste isn't working

this should be fixed in Beta2, I have a testbuild but the servers are currently down to give you the link

this includes [media] pctv452e: move buffer to heap, no mutex · torvalds/linux@48775cb · GitHub
sounds pretty much like your problem, if this works pls give feedback and dmesg | paste (that I could fix it in official)

Ok, the oops is fixed
OVOT

CvH, does the test image you provided use same mechanism for lirc configuration as ever? I can't seem to put my own lircd.conf into /storage/.config/ and use that?

And would you be so kind to reopen this thread again:
thread-4230-post-30640.html#pid30640
As I want to give some feedback regarding the blocking of IIR via gpio

Thx

not too sure. there are some things about lirc recently but honestly no idea, you could wait for LE8 B2 there it should be fixed (if there is a problem)
