| |
The interrupts initially works on the device but they will stop arriving after about 200 interrupts.
On system reboot/shutdown this will cause a long wait (120000 jiffies).
The interrupts on this device got enabled by commit e644b2f498d2 ("tpm, tpm_tis: Enable interrupt test")
Prior to this point the interrupts were not enabled on this machine.
Complements: e644b2f498d2 ("tpm, tpm_tis: Enable interrupt test") Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> --- Hi,
This patch applies on top of mainline since 6.4-rc1 takes about 2 minutes to reboot on this machine, linux-next have e7d3e5c4b1dd tpm/tpm_tis: Disable interrupts for more Lenovo devices
I'm not sure if I shouold send this on top of next or mainline is fine, please let me know the preferred way to get this to 6.4.
Regards, Peter
